from Wikipedia

Stephen Gary Wozniak (/ˈwɒzniæk/; born August 11, 1950), also known by his nickname Woz, is an American technology entrepreneur, electrical engineer, computer programmer, and inventor. In 1976, he co-founded Apple Computer with his early business partner Steve Jobs. Through his work at Apple in the 1970s and 1980s, he is widely recognized as one of the most prominent pioneers of the personal computer revolution.[4]

Key Information

In 1975, Wozniak started developing the Apple I[5]: 150 into the computer that launched Apple when he and Jobs first began marketing it the following year. He was the primary designer of the Apple II, introduced in 1977, known as one of the first highly successful mass-produced microcomputers,[6] while Jobs oversaw the development of its foam-molded plastic case and early Apple employee Rod Holt developed its switching power supply.[7]

With human–computer interface expert Jef Raskin, Wozniak had a major influence over the initial development of the original Macintosh concepts from 1979 to 1981, when Jobs took over the project following Wozniak's brief departure from the company due to a traumatic airplane accident.[8][3] After permanently leaving Apple in 1985, Wozniak founded CL 9 and created the first programmable universal remote, released in 1987. He then pursued several other business and philanthropic ventures throughout his career, focusing largely on technology in K–12 schools, which involved a 1990 initiative to place computers in schools in the former Soviet Union.[3][9]

He has received numerous awards and honors for his work in philanthropy and the tech industry, including an induction into the National Inventors Hall of Fame in 2000.[9] As of June 2024, Wozniak has remained an employee of Apple in a ceremonial capacity since stepping down in 1985.[10][11] In recent years, he has helped fund multiple entrepreneurial efforts dealing in areas such as GPS and telecommunications, flash memory, technology and pop culture conventions, technical education, ecology, satellites and more. In addition to his American citizenship, Wozniak is also a Polish and Serbian citizen.

Early life

[edit]

Stephen Gary Wozniak was born on August 11, 1950, in San Jose, California.[5]: 18 [12][13]: 13 [14]: 27  His mother, Margaret Louise Wozniak (née Kern) (1923–2014), was from Washington state,[15] and his father, Francis Jacob "Jerry" Wozniak (1925–1994) of Michigan,[5]: 18  was an engineer for the Lockheed Corporation.[14]: 1  Wozniak graduated from Homestead High School in 1968, in Cupertino, California.[13]: 25  Steve has one brother, Mark,[16] a former tech executive who lives in Menlo Park. He also has one sister, Leslie, who attended Homestead High School in Cupertino. She is a grant adviser at Five Bridges Foundation, which helps at-risk youths in San Francisco. Leslie said it was her mother who introduced activism to her and her siblings.[17]

The name on Wozniak's birth certificate is "Stephan Gary Wozniak", but his mother said that she intended it to be spelled "Stephen", which is what he uses.[5]: 18  Wozniak is of Polish and German ancestry.[18] In the early 1970s, Wozniak's blue box design earned him the nickname "Berkeley Blue" in the phreaking community.[1][19] Wozniak has credited watching Star Trek and attending Star Trek conventions while in his youth as a source of inspiration for his starting Apple Computer.[20] In his autobiography, iWoz, he also credits the Tom Swift Jr. books as an inspiration for becoming an engineer.[21]

Career

[edit]

Pre-Apple

[edit]

In 1969, Wozniak returned to the San Francisco Bay Area after being expelled from the University of Colorado Boulder in his first year for hacking the university's computer system.[22][23] He re-enrolled at De Anza College in Cupertino before transferring to the University of California, Berkeley, in 1971.[14]: 1  In June of that year, for a self-taught engineering project, Wozniak designed and built his first computer with his friend Bill Fernandez.[14]: 1 

Predating useful microprocessors, screens, and keyboards, and using punch cards and only 20 TTL chips donated by an acquaintance, they named it "Cream Soda" after their favorite beverage. A newspaper reporter stepped on the power supply cable and blew up the computer, but it served Wozniak as "a good prelude to my thinking 5 years later with the Apple I and Apple II computers".[24] Before focusing his attention on Apple, he was employed at Hewlett-Packard (HP), where he designed calculators.[25] It was during this time that he dropped out of Berkeley and befriended Steve Jobs.[26][27]

Wozniak was introduced to Jobs by Fernandez, who attended Homestead High School with Jobs in 1971. Jobs and Wozniak became friends when Jobs worked for the summer at HP, where Wozniak, too, was employed, working on a mainframe computer.[28]

We first met in 1971 during my college years, while he was in high school. A friend said, 'you should meet Steve Jobs because he likes electronics, and he also plays pranks.' So he introduced us.

Steve Wozniak's blue box at the Computer History Museum

Their first business partnership began later that year when Wozniak read an article titled "Secrets of the Little Blue Box" from the October 1971 issue of Esquire, and started to build his own "blue boxes" that enabled one to make long-distance phone calls at no cost.[29][30] Jobs, who handled the sales of the blue boxes, managed to sell some two hundred of them for $150 each, and split the profit with Wozniak.[31][32] Jobs later told his biographer that if it had not been for Wozniak's blue boxes, "there wouldn't have been an Apple."[33]

In 1973, Jobs was working for arcade game company Atari, Inc. in Los Gatos, California.[34] He was assigned to create a circuit board for the arcade video game Breakout. According to Atari co-founder Nolan Bushnell, Atari offered $100 (equivalent to $708 in 2024) for each chip that was eliminated in the machine. Jobs had little knowledge of circuit board design and made a deal with Wozniak to split the fee evenly between them if Wozniak could minimize the number of chips. Wozniak reduced the number of chips by 50, by using RAM for the brick representation. Whilst a lack of scoring or coin mechanisms made Woz's prototype unusable, Jobs was paid the full bonus regardless. Jobs told Wozniak that Atari gave them only $700 and that Wozniak's share was thus $350 (equivalent to $2,500 in 2024).[35][5]: 147–148, 180  Wozniak did not learn about the actual $5,000 bonus (equivalent to $35,400 in 2024) until ten years later. While dismayed, he said that if Jobs had told him about it and had said he needed the money, Wozniak would have given it to him.[36]: 104–107 

In 1975, Wozniak began designing and developing the computer that would eventually make him famous, the Apple I.[37] With the Apple I, Wozniak was largely working to impress other members of the Palo Alto–based Homebrew Computer Club,[38]: 35–38  a local group of electronics hobbyists interested in computing. The club was one of several key centers which established the home hobbyist era, essentially creating the microcomputer industry over the next few decades. Unlike other custom Homebrew designs, the Apple had an easy-to-achieve video capability that drew a crowd when it was unveiled.[39]

Zaltair

[edit]

Wozniak also created the fictional computer Zaltair. Adam Schoolsky and Randy Wigginton helped him to pull it off at the West Coast Computer Conference. It was a parody of the Altair 8800 computer, which was very popular at the time. Steve Wozniak thought of the name because:

The company Zilog had come out with a compatible processor, which they called the Z-80. A few companies using this chip were establishing brands based on Z words. Like ComputerZ or Z-Node or the like.[40]

As a joke, Wozniak decided to print "20,000 brochures" (according to YouTube video "Rare video of Steve Wozniak from 1984 talking about computing, joining Apple and the Mac" filmed at a Cleveland computer club meeting) of a fake product called the 'Zaltair' with a lot of "superlative descriptions of a computer that solved every problem in the world".[40] It advertised, among other things, a new version of the BASIC programming language called "BAZIC", with the ability to "define your own language... a feature we call perZonality".[41]

To help make the ad believable, he included fake trademarks and a shipping label for MITS, the company manufacturing the Altair. Wozniak did not think that this would be an issue, as he had "made sure in advance that MITS would not be at the show." However, it later turned out that a representative from MITS was attending, and had been taking large amounts of their fake brochures.[40] He also made sure the article had a fake quote from Ed Roberts, then president of MITS, which spelled out the name of a rival company, Processor Technology, when looking at the first letter of every word, further ensuring that the article was not traced back to him.

Steve Jobs, Wozniak's close friend at the time, received a copy of the brochure. He fell for it, and even "took pride that the Apple II stacked up well against the Zaltair in the comparison chart". However, he, like many others, did not realize Wozniak had created the brochure until "Woz gave him a framed copy of the brochure as a birthday gift" in 1985.[42]

Apple formation and success

[edit]

Wozniak designed Apple's first products, the Apple I and II computers and he helped design the Macintosh — because he wanted to use them and they didn't exist.

Between Woz and Jobs, Woz was the innovator, the inventor. Steve Jobs was the marketing person.

— Apple employee #12 Daniel Kottke[44]

Everything I did at Apple that was an A+ job and that took us places, I had two things in my favor ... I had no money [and] I had had no training.

— Steve Wozniak in 2010[43]

By March 1, 1976, Wozniak completed the basic design of the Apple I computer.[14]: 5–6  He alone designed the hardware, circuit board designs, and operating system for the computer.[39] Wozniak originally offered the design to HP while working there, but was denied by the company on five occasions.[45] Jobs then advised Wozniak to start a business of their own to build and sell bare printed circuit boards of the Apple I.[14]: 4–6 [38]: 35–38  Wozniak, at first skeptical, was later convinced by Jobs that even if they were not successful they could at least say to their grandchildren that they had had their own company. To raise the money they needed to build the first batch of the circuit boards, Wozniak sold his HP scientific calculator while Jobs sold his Volkswagen van.[14]: 4–6 [38]: 35–38 

On April 1, 1976, Jobs and Wozniak formed the Apple Computer Company (now called Apple Inc.) along with administrative supervisor Ronald Wayne, whose participation in the new venture was short-lived. The two decided on the name "Apple" shortly after Jobs returned from Oregon and told Wozniak about his time spent on an apple orchard there.[46]

After the company was formed, Jobs and Wozniak made one last trip to the Homebrew Computer Club to give a presentation of the fully assembled version of the Apple I.[38]: 39–40  Paul Terrell, who was starting a new computer shop in Mountain View, California, called the Byte Shop,[5] saw the presentation and was impressed by the machine.[36]: 66–67  Terrell told Jobs that he would order 50 units of the Apple I and pay $500 (equivalent to $2,760 in 2024) each on delivery, but only if they came fully assembled, as he was not interested in buying bare printed circuit boards.[14]: 7 [36]: 66–67 

Together the duo assembled the first boards in Jobs's parents' Los Altos home; initially in his bedroom and later (when there was no space left) in the garage. Wozniak's apartment in San Jose was filled with monitors, electronic devices, and computer games that he had developed. The Apple I sold for $666.66. Wozniak later said he had no idea about the relation between the number and the mark of the beast, and that he came up with the price because he liked "repeating digits".[47] They sold their first 50 system boards to Terrell later that year.[clarification needed]

In November 1976, Jobs and Wozniak received substantial funding from a then-semi-retired Intel product marketing manager and engineer named Mike Markkula.[48][14]: 10  At the request of Markkula, Wozniak resigned from his job at HP and became the vice president in charge of research and development at Apple. Wozniak's Apple I was similar to the Altair 8800, the first commercially available microcomputer, except the Apple I had no provision for internal expansion cards. With expansion cards, the Altair could attach to a computer terminal and be programmed in BASIC. In contrast, the Apple I was a hobbyist machine. Wozniak's design included a $25 CPU (MOS 6502) on a single circuit board with 256 bytes of ROM, 4K or 8K bytes of RAM, and a 40-character by 24-row display controller. Apple's first computer lacked a case, power supply, keyboard, and display—all components that had to be provided by the user. Eventually about 200 Apple I computers were produced in total.[49]

An Apple II computer with an external modem

After the success of the Apple I, Wozniak designed the Apple II, the first personal computer with the ability to display color graphics, and BASIC programming language built in.[5] Inspired by "the technique Atari used to simulate colors on its first arcade games", Wozniak found a way of putting colors into the NTSC system by using a US$1 chip,[50] while colors in the PAL system are achieved by "accident" when a dot occurs on a line, and he says that to this day he has no idea how it works.[51] During the design stage, Jobs argued that the Apple II should have two expansion slots, while Wozniak wanted eight.[5] After a heated argument, during which Wozniak threatened that Jobs should "go get himself another computer", they decided to go with eight slots. Jobs and Wozniak introduced the Apple II at the April 1977 West Coast Computer Faire. Wozniak's first article about the Apple II was in Byte magazine in May 1977.[52] It became one of the first highly successful mass-produced personal computers in the world. Wozniak also designed the Disk II floppy disk drive, released in 1978 specifically for use with the Apple II to replace the slower cassette tape storage.

In 1980, Apple went public to instant and significant financial profitability, making Jobs and Wozniak both millionaires. The Apple II's intended successor, the Apple III, released the same year, was a commercial failure and was discontinued in 1984. According to Wozniak, the Apple III "had 100 percent hardware failures", and that the primary reason for these failures was that the system was designed by Apple's marketing department, unlike Apple's previous engineering-driven projects.[53]

An original Macintosh with hardware

During the early design and development phase of the original Macintosh, Wozniak had a heavy influence over the project along with Jef Raskin, who conceived the computer. Later named the "Macintosh 128k", it would become the first mass-market personal computer featuring an integral graphical user interface and mouse. The Macintosh would also go on to introduce the desktop publishing industry with the addition of the Apple LaserWriter, the first laser printer to feature vector graphics.[54] In a 2013 interview, Wozniak said that in 1981, "Steve [Jobs] really took over the project when I had a plane crash and wasn't there."[3][8]

Plane crash and temporary leave from Apple

[edit]

On February 7, 1981, the Beechcraft Bonanza A36TC which Wozniak was piloting (and not qualified to operate[55]) crashed soon after takeoff from the Sky Park Airport in Scotts Valley, California.[56] The airplane stalled while climbing, then bounced down the runway, broke through two fences, and crashed into an embankment. Wozniak and his three passengers—then-fiancée Candice Clark, her brother Jack Clark, and Jack's girlfriend, Janet Valleau—were injured. Wozniak sustained severe face and head injuries, including losing a tooth, and also suffered for the following five weeks from anterograde amnesia, the inability to create new memories. He had no memory of the crash, and did not remember his name while in the hospital or the things he did for a time after he was released.[53][57] He would later state that Apple II computer games were what helped him regain his memory.[5] The National Transportation Safety Board investigation report cited premature liftoff and pilot inexperience as probable causes of the crash.[14]: 28–30 

Wozniak did not immediately return to Apple after recovering from the airplane crash, seeing it as a good reason to leave.[53] Infinite Loop characterized this time: "Coming out of the semi-coma had been like flipping a reset switch in Woz's brain. It was as if in his thirty-year old body he had regained the mind he'd had at eighteen before all the computer madness had begun. And when that happened, Woz found he had little interest in engineering or design. Rather, in an odd sort of way, he wanted to start over fresh."[58]: 322 

UC Berkeley and US Festivals

[edit]
Wozniak in 1983

Later in 1981, after recovering from the plane crash, Wozniak re-enrolled at UC Berkeley to complete his Electrical Engineering and Computer Sciences degree that he started there in 1971 (and which he would finish in 1986).[59] Because his name was well known at this point, he enrolled under the name Rocky Raccoon Clark, which is the name listed on his diploma,[3][10][60] although he did not officially receive his degree in electrical engineering and computer sciences until 1987.[26][3]

In May 1982 and 1983, Wozniak, with help from professional concert promoter Bill Graham, founded the company Unuson, an abbreviation of "unite us in song",[61] which sponsored two US Festivals, with "US" pronounced like the pronoun, not as initials. Initially intended to celebrate evolving technologies, the festivals ended up as a technology exposition and a rock festival as a combination of music, computers, television, and people. After losing several million dollars on the 1982 festival, Wozniak stated that unless the 1983 event turned a profit, he would end his involvement with rock festivals and get back to designing computers.[62] Later that year, Wozniak returned to Apple product development, desiring no more of a role than that of an engineer and a motivational factor for the Apple workforce.[5][58]: 323–324 

Return to Apple product development

[edit]

Starting in the mid-1980s, as the Macintosh experienced slow but steady growth, Apple's corporate leadership, including Steve Jobs, increasingly disrespected its flagship cash cow Apple II series—and Wozniak along with it. The Apple II division—other than Wozniak—was not invited to the Macintosh introduction event, and Wozniak was seen kicking the dirt in the parking lot.[63] Although Apple II products provided about 85% of Apple's sales in early 1985, the company's January 1985 annual meeting did not mention the Apple II division or its employees, a typical situation that frustrated Wozniak.[64]

Final departure from Apple workforce

[edit]

Even with the success he had helped to create at Apple, Wozniak believed that the company was hindering him from being who he wanted to be, and that it was "the bane of his existence".[65] He enjoyed engineering, not management, and said that he missed "the fun of the early days".[10] As other talented engineers joined the growing company, he no longer believed he was needed there.[5] By early 1985, Wozniak left Apple again and sold most of his stock.[64] Media coverage attributed his departure to disagreements with Apple management, quoting his statement that Apple had "been going in the wrong direction for the last five years",[64] but Wozniak later objected to this portrayal and stated that he left primarily because he was excited to start CL 9 and recapture the fun of developing a new technology.[5]: 266

The Apple II platform financially carried the company well into the Macintosh era of the late 1980s;[64] it was made semi-portable with the Apple IIc of 1984, and was extended, with some input from Wozniak, by the 16-bit Apple IIGS of 1986, and was discontinued altogether when the Apple IIe was discontinued on November 15, 1993 (although the Apple IIe card, which allowed compatible Macintosh computers to run Apple II software and use certain Apple II peripherals, was produced until May 1995).

Post-Apple

[edit]

After his career at Apple, Wozniak founded CL 9 in 1985, which developed and brought the first programmable universal remote control to market in 1987, called the "CORE".[5] Beyond engineering, Wozniak's second lifelong goal had always been to teach elementary school because of the important role teachers play in students' lives. Eventually, he did teach computer classes to children from the fifth through ninth grades, and teachers as well.[60][65] Unuson continued to support this, funding additional teachers and equipment.[61]

In 2001, Wozniak founded Wheels of Zeus (WOZ)[66] to create wireless GPS technology to "help everyday people find everyday things much more easily". In 2002, he joined the board of directors of Ripcord Networks, Inc., joining Apple alumni Ellen Hancock, Gil Amelio, Mike Connor, and Wheels of Zeus co-founder Alex Fielding in a new telecommunications venture. Later the same year he joined the board of directors of Danger, Inc., the maker of the Hip Top.

In 2006, Wheels of Zeus was closed, and Wozniak founded Acquicor Technology, a holding company for acquiring technology companies and developing them, with Apple alumni Hancock and Amelio. From 2009 through 2014 he was chief scientist at Fusion-io.[67] In 2014 he became chief scientist at Primary Data, which was founded by some former Fusion-io executives.[68] Silicon Valley Comic Con (SVCC) is an annual pop culture and technology convention at the San Jose McEnery Convention Center in San Jose, California. The convention was co-founded by Wozniak and Rick White, with Trip Hunter as CEO.[69] Wozniak announced the annual event in 2015 along with Marvel legend Stan Lee.[70] In October 2017, Wozniak founded Woz U, an online educational technology service for independent students and employees.[71] As of December 2018, Woz U was licensed as a school with the Arizona state board.[72]

Though permanently leaving Apple as an active employee in 1985, Wozniak chose to never remove himself from the official employee list, and continues to represent the company at events or in interviews.[10] Today he receives a stipend from Apple for this role, estimated in 2006 to be US$120,000 per year.[5][10][73] He is also an Apple shareholder.[74] He maintained a friendly acquaintance with Steve Jobs until Jobs's death in October 2011.[75] However, in 2006, Wozniak stated that he and Jobs were not as close as they used to be.[76]

In a 2013 interview, Wozniak said that the original Macintosh "failed" under Steve Jobs, and that it was not until Jobs left that it became a success. He called the Apple Lisa group the team that had kicked Jobs out, and that Jobs liked to call the Lisa group "idiots for making [the Lisa computer] too expensive". To compete with the Lisa, Jobs and his new team produced a cheaper computer, one that, according to Wozniak, was "weak", "lousy" and "still at a fairly high price". "He made it by cutting the RAM down, by forcing you to swap disks here and there", says Wozniak. He attributed the eventual success of the Macintosh to people like John Sculley "who worked to build a Macintosh market when the Apple II went away".[8]

At the end of 2020, Wozniak announced the launch of a new company helmed by him, Efforce. Efforce is described as a marketplace for funding ecologically friendly projects. It used a WOZX cryptocurrency token for funding and blockchain to redistribute the profit to token holders and businesses engaged on the platform.[77] In September 2021, it was reported that Wozniak was also starting a company alongside co-founder Alex Fielding named Privateer Space to address the problem of space debris.[78][79] Privateer Space debuted the first version of its space traffic monitoring software on March 1, 2022.[80] In 2024, Wozniak sued YouTube in respect to a scam that was being circulated on the platform using his likeness. Later, he won after a San Jose appeals court ruled YouTube was liable for failing to combat it.[81]

Inventions

[edit]

Wozniak is listed as the sole inventor on the following Apple patents:

  • US Patent No. 4,136,359: "Microcomputer for use with video display"[82]—for which he was inducted into the National Inventors Hall of Fame.
  • US Patent No. 4,210,959: "Controller for magnetic disc, recorder, or the like"[83]
  • US Patent No. 4,217,604: "Apparatus for digitally controlling PAL color display"[84]
  • US Patent No. 4,278,972: "Digitally-controlled color signal generation means for use with display"[85]

Other

[edit]

In 1990, Wozniak helped found the Electronic Frontier Foundation, providing some of the organization's initial funding[86][87][88] and serving on its founding Board of Directors.[86] He is the founding sponsor of the Tech Museum, Silicon Valley Ballet and Children's Discovery Museum of San Jose.[3]

Views on artificial superintelligence

[edit]

In March 2015, Wozniak stated that he had originally dismissed Ray Kurzweil's opinion that machine intelligence would outpace human intelligence. But within several decades, Wozniak had changed his mind:

I agree that the future is scary and very bad for people. If we build these devices to take care of everything for us, eventually they'll think faster than us and they'll get rid of the slow humans to run companies more efficiently.

Wozniak stated that he had started to identify a contradictory sense of foreboding about artificial intelligence, while still supporting the advance of technology.[89] By June 2015, Wozniak changed his mind again, stating that a superintelligence takeover would be good for humans:

They're going to be smarter than us and if they're smarter than us then they'll realise they need us ... We want to be the family pet and be taken care of all the time ... I got this idea a few years ago and so I started feeding my dog filet steak and chicken every night because 'do unto others'.[90][91]

In 2016, Wozniak changed his mind again, stating that he no longer worried about the possibility of superintelligence emerging because he is skeptical that computers will be able to compete with human "intuition": "A computer could figure out a logical endpoint decision, but that's not the way intelligence works in humans". Wozniak added that if computers do become superintelligent, "they're going to be partners of humans over all other species just forever".[92][93][94]

Wozniak signed a 2023 open letter from the Future of Life Institute calling for "all AI labs to immediately pause for at least 6 months the training of AI systems more powerful than GPT-4".[95] In an interview to the BBC in May 2023 Wozniak said that AI may make scams more difficult to detect, noting that "AI is so intelligent it's open to the bad players, the ones that want to trick you about who they are".[96]

Personal life

[edit]
Wozniak and friend Kathy Griffin in 2008

Wozniak lives in Los Gatos, California. He applied for Australian citizenship in 2012, and has stated that he would like to live in Melbourne, Australia, in the future.[97] Wozniak has been referred to frequently by the nickname "Woz", or "The Woz"; he has also been called "The Wonderful Wizard of Woz" and "The Second Steve" (in regard to his early business partner and longtime friend, Steve Jobs).[98] "WoZ" (short for "Wheels of Zeus") is the name of a company he founded in 2002; it closed in 2006.[99]

Wozniak describes his impetus for joining the Freemasons in 1979 as being able to spend more time with his then-wife, Alice Robertson, who belonged to the Order of the Eastern Star, associated with the Masons. He was initiated in 1979 at Charity Lodge No. 362 in Campbell, California, now part of Mt. Moriah Lodge No. 292 in Los Gatos.[100] Today he is no longer involved: "I did become a Freemason and know what it's about but it doesn't really fit my tech/geek personality. Still, I can be polite to others from other walks of life. After our divorce was filed I never attended again but I did contribute enough for a lifetime membership."[101]

Wozniak was married to slalom canoe gold-medalist Candice Clark from June 1981 to 1987. They have three children together, the youngest being born after their divorce was finalized.[102][103] After a high-profile relationship with actress Kathy Griffin, who described him on Tom Green's House Tonight in 2008 as "the biggest techno-nerd in the Universe", Wozniak married Janet Hill, his current spouse.[104] On his religious views, Wozniak has called himself an "atheist or agnostic".[105][106]

He is a member of a Segway Polo team, the Silicon Valley Aftershocks,[107] and is considered a "super fan" of the NHL ice hockey team San Jose Sharks.[108] In 1998, he co-authored with Larry Wilde The Official Computer Freaks Joke Book. In 2006, he co-authored with Gina Smith his autobiography, iWoz: From Computer Geek to Cult Icon: How I Invented the Personal Computer, Co-Founded Apple, and Had Fun Doing It. The book made The New York Times Best Seller list.[3]

Wozniak has discussed his personal disdain for money and accumulating large amounts of wealth. He told Fortune magazine in 2017, "I didn't want to be near money, because it could corrupt your values ... I really didn't want to be in that super 'more than you could ever need' category." He also said that he only invests in things "close to his heart". When Apple first went public in 1980, Wozniak offered $10 million of his own stock to early Apple employees, something Jobs refused to do.[109] In 2017, Wozniak received a Polish citizenship and visited Poland to meet with government and technology industry representatives and to visit his father’s hometown.[110]

He has the condition prosopagnosia (face blindness).[111] Wozniak has expressed support for the right to repair movement. In July 2021, he made a Cameo video in response to right to repair activist Louis Rossmann, in which he described the issue as something that has "really affected me emotionally", and credited Apple's early breakthroughs to open technology of the 1970s.[112][113] In November 2023, Wozniak suffered a minor stroke while preparing to speak at a conference in Mexico City. He was hospitalized briefly before returning home.[114][115] Wozniak became a Serbian citizen in December 2023.

Early Life and Education

Childhood and Family Background

Stephen Gary Wozniak was born on August 11, 1950, in . He was the eldest of three children born to Jacob Francis "Jerry" Wozniak, an electrical engineer who worked at Lockheed, and Margaret Elaine Kern, of Swiss-German descent. His father, whose family had Polish roots tracing back to (then part of , now ), had immigrated to the at age seven. The family resided in the region, an area that would later emerge as the heart of . Wozniak's upbringing was marked by his father's professional influence in , providing an environment conducive to technical curiosity, though specific childhood anecdotes emphasize a stable, middle-class household rather than overt privilege. His younger brother, Mark, pursued a in as an executive, while details on the third remain less documented in primary accounts. The family's emphasis on and problem-solving, instilled by Jerry Wozniak's engineering ethos, shaped early family dynamics without reliance on external narratives of exceptionalism.

Initial Interests in Electronics and Hacking

Wozniak's fascination with emerged in childhood, influenced by his father, Francis Jacob "Jerry" Wozniak, an electrical engineer at Lockheed who patiently explained fundamental principles, such as the flow of electrons through wires to produce light in a , fostering a deep understanding of causal mechanisms in devices. By , he was disassembling and reassembling calculators and radios, honing practical skills through hands-on experimentation. In , around 1961, Wozniak obtained a ham radio license, constructing his own receiver from components, which introduced him to circuits and . He soon built additional devices from scratch, including a for measuring electrical potentials and simple games relying on basic logic circuits, demonstrating an early aptitude for minimizing components while achieving functionality. To create a programmable , he mastered and synthesized logic gates using discrete transistors, a process that required iterative prototyping and of gate arrays. During junior high school in , Wozniak constructed a 10-bit binary adder using hundreds of transistors and diodes, entering it in a where it earned recognition for its computational efficiency. This project exemplified his hacking ethos: optimizing designs to reduce parts count, akin to solving puzzles by eliminating in logic paths, often sketching circuits on paper before physical assembly. By high school in the mid-1960s, Wozniak had advanced to designing full computers conceptually, recreating architectures of existing machines like the PDP-8 minicomputer using fewer gates than manufacturers, a self-taught developed through library books on digital logic and repeated mental simulations of ALU operations and memory addressing. He claimed to have diagrammed "hundreds" of such systems, prioritizing elegance in gate minimization over mere replication, which laid the groundwork for his later hardware innovations by emphasizing verifiable, low-level causality in silicon implementations. These pursuits were largely solitary, driven by intrinsic curiosity rather than formal instruction, as he bypassed school curricula to explore transistor-level hacking.

Formal Education and Early Challenges

Wozniak graduated from Homestead High School in , in 1968, where he excelled in mathematics and demonstrated early aptitude in electronics through self-directed projects. He then enrolled at the for the 1968–1969 academic year, intending to study engineering, but faced immediate setbacks due to his unauthorized access to the university's computer system. Using the mainframe to send prank messages to dorm residents, Wozniak was expelled after accruing significant unauthorized usage, which also resulted in an unpaid computing bill estimated at around $10,000 at the time—equivalent to over $50,000 in current dollars—highlighting his prioritization of exploratory hacking over institutional rules and financial prudence. Financial pressures from the incident and family support limitations prompted Wozniak's return to , where he enrolled at De Anza Community College in Cupertino for his sophomore year to continue lower-division coursework at reduced cost. In 1971, he transferred to the , pursuing and , but dropped out after approximately two years to work full-time at , seeking income to sustain himself amid ongoing economic challenges and a stronger pull toward practical than structured academia. This pattern reflected broader early hurdles: Wozniak's self-taught expertise in often clashed with formal curricula, leading to disengagement, while his resourcefulness in unauthorized computing foreshadowed innovations but incurred institutional penalties. Wozniak delayed resuming formal studies until after a 1981 plane crash that caused temporary memory loss, prompting him to re-enroll at Berkeley under the pseudonym "Rocky Raccoon Clark" to avoid publicity as an Apple co-founder. He completed his Bachelor of Science in Electrical Engineering and Computer Science in 1986, 18 years after starting college, underscoring the causal tension between his independent inventive drive—which yielded breakthroughs like the Apple I—and the rigid timelines of traditional education. Despite these obstacles, Wozniak later emphasized that formal credentials held limited value compared to hands-on problem-solving, a view informed by his career success without early degrees.

Pre-Apple Professional Beginnings

Employment at

Stephen Gary Wozniak joined in 1971, shortly after dropping out of the during his senior year. At the company's Palo Alto facility, he worked as an engineer in the calculator division, focusing on designing custom integrated circuits and chips for scientific calculators. This role provided him with access to advanced engineering tools and teams, honing his skills in and logic design, which he later credited as foundational to his computer innovations. Wozniak's designs contributed to several post-HP-35 models, including the HP-45 (released 1973), HP-55 (1975), programmable calculator (1974), and HP-80 financial calculator (1975). These efforts involved optimizing chip architectures for functions like programmable memory and processing, reflecting HP's emphasis on compact, high-performance devices during the early calculator boom. His work elevated him to a full position, where he tackled complex challenges such as efficient arithmetic logic units. During his tenure, Wozniak prototyped a personal in 1975 using the microprocessor, incorporating video display and keyboard interfaces on a minimal board. He pitched the concept to HP management multiple times in 1976, proposing it as a low-cost appliance for hobbyists, but the company declined, citing lack of market potential and internal priorities on calculators and minicomputers. This decision allowed Wozniak to retain rights to the design. To finance initial production after resigning from HP later that year, he sold his personal calculator for $500.

Phone Phreaking and the Blue Box Invention

In the early 1970s, Steve Wozniak participated in , an illicit activity involving the manipulation of analog networks to place unauthorized long-distance calls by generating specific control tones that mimicked the signaling tones used by AT&T's switching systems, such as the 2600 Hz supervisory tone. Phone phreaking exploited the vulnerabilities of the era's electromechanical phone infrastructure, which relied on in-band multifrequency tones for routing and billing, allowing phreakers to insert themselves into call trunks and direct connections without incurring charges. Wozniak's interest was sparked by the October 1971 Esquire magazine article "Secrets of the Little Blue Box" by Ron Rosenbaum, which detailed the techniques and devices used by early phreakers like John Draper. Motivated by curiosity about the phone system's architecture, Wozniak designed and built his own blue box around 1971–1972, creating a compact digital device that synthesized precise tones using discrete transistor-transistor logic (TTL) integrated circuits and a minimal set of components, including oscillators for generating the required dual-tone multifrequency (DTMF) signals and other control frequencies. This design improved upon earlier analog blue boxes by reducing size, cost, and complexity, incorporating a keyboard interface for selecting tones and a speaker or direct handset connection for playback. Wozniak's enabled him to make experimental free calls, including international ones where he impersonated figures like to connect with operators in places such as the Vatican, primarily to explore the system's limits rather than for commercial gain. In late 1971, Wozniak partnered with , who handled marketing and sales; they produced and sold approximately 200 units at $150 each, earning about $6,000 in their first joint business venture, though operations ceased without legal repercussions as authorities did not intervene. This episode honed their skills in , prototyping, and entrepreneurship, predating the founding of Apple by several years, and exemplified Wozniak's engineering approach of reverse-engineering complex systems through first-hand experimentation.

Founding and Innovations at Apple

Formation of Apple Computer

Steve and formally established the Apple Computer Company as a partnership on April 1, 1976, alongside , to commercialize Wozniak's single-board computer design. The initiative stemmed from Wozniak's demonstration of the prototype at the in July 1976, which garnered interest from early adopters and retailers like the Byte Shop. Jobs, recognizing the commercial potential, convinced Wozniak to shift from hobbyist sharing of schematics to selling assembled units, marking a pivotal transition from Wozniak's engineering focus to a venture. To fulfill an initial order of 50 motherboards from the Byte Shop at $500 each, requiring $25,000 in parts, Jobs and Wozniak secured a from a local after assembling a and demonstrating viability. Lacking substantial capital, Jobs sold his microbus for approximately $1,500, while Wozniak sold his calculator for $500, providing seed funds for components and operations conducted in Jobs' parents' garage in . contributed administrative expertise and drafted the partnership agreement but exited within weeks, selling his 10% stake back for $800 amid concerns over liability. By January 3, 1977, with investor providing $250,000 in seed funding and business guidance, the partnership incorporated as Apple Computer, Inc., enabling scaled production and formal structure. This incorporation followed successful sales of around 200 units, each priced at $666.66, validating the model's market demand despite its bare-bones configuration lacking a case, keyboard, or display. Wozniak's technical innovations, including integration of video output and keyboard interfaces on a single board, underpinned the company's early viability, while Jobs emphasized user accessibility over Wozniak's initial preference for open-source dissemination.

Design and Launch of Apple I

Steve Wozniak designed the in 1975 as a project, drawing inspiration from the while aiming for greater integration and efficiency. The design centered on the microprocessor operating at 1.023 MHz, with 4 KB of dynamic RAM expandable to 8 KB on the board and support for up to 64 KB total via expansion. It featured a video interface capable of displaying 24 lines of 40 characters on a standard , minimizing the chip count through custom logic and including provisions for loading a from . Wozniak's approach prioritized first-principles to reduce costs and complexity, resulting in a single-board system without a built-in keyboard, case, or display. Wozniak completed the basic design by March 1976 while employed at , which rejected his proposal to produce it. He hand-built prototypes in his spare time, demonstrating one at the meeting in , in July 1976, where it garnered enthusiasm from fellow hobbyists for its video capabilities and accessibility. Steve Jobs recognized commercial potential and convinced Wozniak to sell the machines rather than give away schematics, as was common in the club. The pivotal first order came from , owner of the Byte Shop in Mountain View, who committed to 50 units at $500 each after seeing a demo, providing crucial capital despite Jobs and Wozniak lacking inventory. The Apple I launched for sale in July 1976 at $666.66 per unit—a price Wozniak selected for its repeating digits and to achieve a one-third markup over the $500 wholesale cost. Marketed as an assembled ready for user-supplied peripherals like keyboards and TVs, it targeted hobbyists and early adopters. Around 200 units were ultimately produced, with Wozniak assembling about 175 himself in Jobs' garage. This launch marked Apple's entry into the personal computing market, validating Wozniak's design innovations despite the rudimentary form factor.

Development and Impact of Apple II

Steve Wozniak designed the Apple II hardware as an evolution from the , prioritizing affordability, reliability, and user convenience through minimalist engineering and off-the-shelf components. The system centered on a microprocessor clocked at 1 MHz, with initial 4 KB of RAM expandable to 48 KB via cheaper dynamic RAM chips, and a 12 KB ROM containing for immediate usability without loading from tape. Wozniak innovated by synchronizing video signal generation directly with the CPU clock cycle—dividing the 14.318 MHz colorburst frequency to produce 280x192 resolution color graphics and a —eliminating the need for costly dedicated video hardware and enabling composite TV output. Additional features included a built-in speaker for simple sound generation via software toggling, game paddles, and an eight-slot expansion bus with prioritized interrupts and DMA support, allowing modular peripherals while keeping the base unit self-contained with its own keyboard and . Development accelerated in 1976 after Wozniak's Homebrew Computer Club demonstrations of the Apple I, with the prototype incorporating these elements into a single plastic-cased board to reduce assembly costs and improve accessibility over hobbyist kits. Production boards began shipping on May 10, 1977, following refinements detailed in Wozniak's BYTE magazine article, which emphasized the design's focus on low component count for mass production viability. Priced at $1,298 for the 4 KB configuration, the Apple II launched publicly in June 1977 as Apple's first complete consumer product. Wozniak later extended the platform's storage capabilities, developing the Disk II controller and drive in a crash effort starting December 1977 to replace slow cassette tapes with 140 KB floppy disks, using a single-chip design to minimize hardware. The Apple II's integrated design and expandability propelled its market adoption, achieving rapid sales growth—reaching monthly revenues of $84,000 shortly after launch and nearing $1 million annually by late 1977—positioning Apple as a personal computing leader. Its color , , and slot architecture enabled diverse applications, bootstrapping markets for , games, and peripherals in homes and schools. , the pioneering spreadsheet program released for the in 1979, served as a "killer app" by automating for businesses, significantly boosting demand and credited with accelerating Apple's success more than any other factor, as many users bought the machine specifically for it. This ecosystem spurred over 15,000 third-party programs and influenced industry standards for user-friendly, versatile personal computers, sustaining the Apple II line's relevance into the 1990s despite competition from PCs.

Internal Conflicts and Departures

Following the success of the , Wozniak took a from Apple in early 1981 to enroll at the , seeking to complete his degree. On February 7, 1981, he piloted a A36TC that crashed shortly after takeoff from Scotts Valley Airport in , resulting in minor injuries to all four occupants, including loss for Wozniak. The accident, attributed to Wozniak's inexperience as a pilot, sidelined him from Apple for approximately two years during his recovery and studies, during which assumed leadership of the Macintosh project. Prior to the crash, internal tensions had emerged between Wozniak and Jobs over philosophies. Wozniak advocated for open, user-expandable systems, such as proposing eight expansion slots for the , while Jobs favored more controlled, integrated designs; this clash contributed to flaws in the , including its fanless cooling system, which led to overheating and market failure. These differences highlighted a broader divergence: Wozniak's emphasis on accessibility and sharing innovations contrasted with Jobs's push toward , closed ecosystems, fostering frustration as Jobs overrode practical input. Upon returning to Apple around 1983, Wozniak grew dissatisfied with the company's shift toward the Macintosh, which he later described as a "lousy product" due to its limitations compared to the 's expandability and reliability. Apple's deprioritization of the line, which Wozniak had engineered and which remained a , further alienated him, as the division received insufficient resources amid the focus on Macintosh development. Wozniak also perceived the growing corporate as stifling the collaborative "" of Apple's early garage days, and Jobs's confrontational —described by Wozniak as directly challenging employees and alienating top talent—exacerbated the environment, with many creative Macintosh team members vowing never to work under Jobs again. On February 6, 1985, Wozniak resigned from his full-time role at Apple, citing a sense of being unneeded amid the influx of younger engineers and the erosion of his influence on core projects. He expressed that Apple had become "the bane of his existence," reflecting cumulative frustrations with its direction over the prior five years, though he retained a ceremonial employee status and continued holding significant stock. This departure preceded Jobs's own exit in September 1985 but stemmed more from Wozniak's personal misalignment with the company's evolution than direct interpersonal rupture, as their differing visions—Wozniak's hacker ethos versus Jobs's market-driven ambition—had long diverged without irreparable personal animosity.

Post-Apple Career Trajectory

Temporary Return to Apple and US Festivals

Following his recovery from a private plane crash on February 7, 1981, which caused temporary , Steve Wozniak took a from Apple to enroll at the , and focus on personal interests. He returned to Apple in 1982 in an engineering capacity, declining promotions to management roles to concentrate on hardware design and technical contributions rather than business operations. During this period, Wozniak continued to receive the National Medal of Technology from President in 1985 for his earlier innovations, though specific new hardware projects from 1982 to 1985 were limited compared to his foundational work on the . He stepped away from active employment at Apple later that year, while remaining on the company payroll indefinitely as a symbolic co-founder. Concurrent with his engineering role at Apple, Wozniak organized the US Festivals through his company Unuson Corporation, aiming to blend demonstrations, and cultural unity in the early . The first event occurred September 3–5, 1982, at in , drawing approximately 400,000 attendees over three days despite triple-digit heat. Funded primarily by Wozniak's proceeds from selling Apple shares post-IPO, the festival cost around $10–12 million and featured rock acts including the , Crosby, Stills & Nash, , and , alongside technology exhibits showcasing emerging computers and gadgets. Bill Graham handled talent booking, with stages emphasizing multimedia production, but logistical challenges like dust storms and inadequate facilities marred the experience for some. Undeterred by initial losses estimated at $5–6 million for the event, Wozniak hosted a larger second on May 28–30, 1983, expanding to themed days: New Wave Day (with acts like , , and Missing Persons), Heavy Metal Day (featuring , Scorpions, and ), and Rock Day (including and Triumph, though some performers like canceled). Attendance reached about 500,000, with enhanced tech tents displaying innovations like early personal computers, but total costs exceeded $20 million across both festivals, resulting in significant financial losses for Wozniak personally. The events highlighted Wozniak's vision of technology's societal potential but underscored his limited experience in large-scale event production, leading Unuson to pivot away from further festivals.

Educational and Philanthropic Ventures

Following his departure from Apple in 1985, Wozniak invested substantial personal resources in K-12 , emphasizing hands-on technology integration. In the late , he adopted the Los Gatos School District in , targeting fifth through eighth grades by supplying students and teachers with state-of-the-art equipment and promoting in . He directly taught classes to students in fifth through ninth grades, as well as to district educators, starting around 1990. This included practical instruction, such as leading a fifth-grade session in 1995. Wozniak also donated computers and related technology to support school programs. In October 2017, Wozniak launched Woz U, an online platform providing self-paced training in , cybersecurity, and other tech skills for independent learners and corporate employees. The venture expanded to K-12 through affiliated programs like Woz ED, which deliver STEM curricula and career pathways to foster early tech proficiency and employment readiness. These efforts align with Wozniak's advocacy for practical, beyond-traditional-schoolroom education to build technical competence.

Later Business Activities and Investments

In 1985, shortly after his permanent departure from Apple, Wozniak founded to develop advanced , culminating in the release of the CORE UC-100 in 1987, recognized as the world's first programmable control capable of learning and storing codes from multiple devices. The company's innovations in remote led to its acquisition by other firms, though specific sale details remain limited in . Wozniak launched Wheels of Zeus (WOZ) in 2001, focusing on wireless GPS-enabled hardware to enable location tracking of personal items like keys or pets through a wristwatch-like device paired with tags. Despite prototyping functional systems demonstrated at events like DEMO 2004, the venture struggled with market adoption and funding, leading to its closure in 2006, after which assets including patents were acquired by ZonTrak for applications. In December , Wozniak co-founded Efforce, a -based platform designed to tokenize and trade verifiable savings from green projects, aiming to incentivize sustainable initiatives by connecting investors with certified reductions in carbon emissions. The company raised initial funding through token sales but faced challenges typical of early-stage ventures amid regulatory scrutiny. By 2021, Wozniak had taken on the role of co-founder and president at Privateer Space, a startup developing technology for mapping and deorbiting space debris to mitigate collision risks in , with initial missions planned using small satellites equipped with sensors and propulsion systems. This involvement reflects his ongoing interest in practical solutions for emerging technical challenges, though the company's progress has been incremental amid the competitive space sustainability sector. Throughout these years, Wozniak has engaged in selective angel investing, prioritizing ventures with strong technical fundamentals over speculative hype, as evidenced by his criteria of evaluating product utility and team expertise before committing capital; notable personal holdings include diversified stocks in established firms like , Nike, and Disney, contributing to his estimated exceeding $100 million.

Technical Contributions and Inventions

Hardware Designs Beyond Apple

Following his permanent departure from Apple in 1985, Wozniak founded , a company dedicated to innovation, and personally designed the CORE UC-100, recognized as the first programmable universal remote control, which debuted in 1987. This handheld device featured learning capabilities, enabling it to capture and replicate signal patterns from proprietary remotes via a serial interface for programming on a computer, thus consolidating control over televisions, VCRs, and other appliances into one unit that retailed for approximately $300. Priced as a premium product due to its advanced microcontroller-based architecture, the CORE emphasized engineer-oriented customization over user-friendly interfaces, reflecting Wozniak's technical focus, though production was limited and the company folded shortly after launch amid market challenges. In 2001, Wozniak launched Wheels of Zeus (WOZ), aiming to develop low-cost wireless hardware for everyday location tracking without relying on cellular infrastructure. The firm's prototypes included wrist-mounted devices integrating GPS receivers with 900 MHz RF ID tags and ad-hoc networking protocols to monitor items like keys or vehicles, alerting users via WiFi hotspots when objects moved beyond a set range or when a started without authorization. These battery-powered units prioritized affordability and simplicity over full features, with Wozniak envisioning grassroots networks of volunteered access points for , but commercialization stalled due to technological and adoption hurdles. WOZ ceased operations in 2006 without releasing consumer products, though its concepts presaged later wearable tracking technologies.

Software and Systems Innovations

Steve Wozniak authored , a compact interpreter designed specifically for the and early computers, completing its core implementation by mid-1976 prior to finalizing the hardware. This integer-only dialect prioritized memory efficiency, fitting within approximately 4 kilobytes of ROM to enable immediate usability on resource-constrained systems powered by the microprocessor, eschewing floating-point operations to avoid computational overhead and larger code size. Wozniak cross-assembled the code on a PDP-11 , simulating the target environment to verify functionality without a physical , demonstrating foresight in software-hardware co-design. Integer BASIC included innovative extensions tailored to the Apple II's color graphics capabilities, such as commands for plotting points, drawing lines, and handling game paddles, which Wozniak integrated after initial deployment to support visual applications like Breakout clones. These features, added iteratively based on user feedback, expanded BASIC's utility beyond text-based computation, fostering early software ecosystems for and entertainment; by 1977, it powered demonstrations at the West Coast Computer Faire, where the debuted with the interpreter built-in. The interpreter's tokenized input and direct execution model minimized latency, making it suitable for real-time interactions on machines with 4-48 KB RAM configurations. Complementing BASIC, Wozniak developed the Apple I's ROM-based machine monitor, a low-level interface program released in 1976 that facilitated , , and direct entry of assembly via input, reducing setup barriers compared to contemporary kits requiring external terminals and loaders. This monitor, ported and refined for the in , supported tape-based program loading and self-diagnostic routines, enhancing system reliability and accessibility for non-expert users; it occupied about 1 KB of ROM and influenced subsequent firmware designs by emphasizing simplicity and extensibility. Wozniak's approach—writing all foundational from scratch—ensured tight integration with hardware, as seen in the Apple II's interrupt-driven architecture that allowed seamless BASIC execution alongside peripherals. Wozniak's software innovations extended to firmware for storage systems, including the 1978 controller, where he optimized the 6502-based soft for reliable 5.25-inch floppy operations at 48 KB/s transfer rates, enabling Apple DOS compatibility without dedicated hardware processors. This design halved sector times through bit-level encoding efficiency, supporting up to 140 KB per disk and catalyzing ; it processed 256-byte sectors via software loops, a pragmatic choice that scaled with the Apple II's 1 MHz clock. By open-sourcing schematics and code snippets, Wozniak encouraged third-party adaptations, indirectly boosting applications like , though he did not author himself. These contributions prioritized causal efficiency—minimalist code yielding maximal utility—over feature bloat, aligning with empirical constraints of .

Patents and Long-Term Influence on Computing

Wozniak holds four U.S. patents as the sole inventor, primarily related to video display systems and storage controllers integral to early Apple computers. U.S. Patent No. 4,136,359, issued on January 23, 1979, covers a system with a video generator enabling color and high-resolution graphics on standard raster-scanned cathode-ray tube displays, utilizing a counter at an odd submultiple of the color subcarrier frequency to align vertical color graphics and mitigate phase reversal issues between scan lines. This design underpinned the Apple II's graphics capabilities, allowing for 6-color display and text modes that distinguished it from contemporaries. U.S. Patent No. 4,210,959, issued on July 1, 1980, describes a controller for interfacing digital computers with magnetic disc recorders, such as floppy disks, featuring track selection via computed velocity profiles and soft-sector synchronization without additional hardware, minimizing CPU involvement in data access. This innovation enabled the low-cost drive for the , achieving reliable 140KB storage per side using off-the-shelf components and self-clocking techniques, which reduced manufacturing costs and facilitated widespread data handling in personal computing.

The , embodying these technologies, sold approximately 6 million units from 1977 to 1993, establishing the viability of color graphics, expandable slots for peripherals, and integrated storage, thereby catalyzing the software ecosystem with applications like and inspiring industry standards for user-accessible hardware. Wozniak's designs influenced subsequent systems, including Macintosh development through his input on human-computer interfaces, promoting intuitive, hobbyist-friendly computing that shifted the paradigm from institutional mainframes to individual ownership and innovation.

Philanthropy and Public Service

Charitable Donations and Causes

Wozniak has directed substantial portions of his Apple-derived wealth toward charitable causes emphasizing , technological access, and , often prioritizing unrestricted giving over personal recognition. In 1980, shortly after Apple's , he distributed shares valued at approximately $10 million to early employees, students, and others who had supported the company's formative efforts, reflecting his aversion to wealth accumulation. A key focus has been advocacy for digital rights; in 1990, Wozniak co-founded the (EFF), contributing initial funding to promote online privacy, free expression, and resistance to government overreach in technology. He also served as a founding sponsor that year for the Tech Museum of Innovation, providing seed money to foster science and technology through interactive exhibits. Wozniak extended support to arts and initiatives, including founding sponsorship of the Silicon Valley Ballet and the Children’s Discovery Museum of San Jose in 1990, both aimed at enriching community cultural and educational resources. Internationally, he sponsored computer donations to schools in the USSR during the same period to bridge technological gaps in education. Domestically, his contributions included providing state-of-the-art computers and equipment to public schools, such as those in the Los Gatos School District starting in 1996, to enhance student learning without formal conditions. His approach to philanthropy underscores a preference for personal involvement over large-scale foundations, valuing donated time—such as eight years teaching at a public school with free computers for students—above monetary gifts alone. Wozniak has described this ethos as giving "with ," trusting recipients' judgment while funding scholarships, museums, and underprivileged tech access, having reportedly dispersed all original Apple proceeds to such ends.

Establishment of Educational Programs

In 1978, Wozniak led a campaign to distribute computers to schools across the , emphasizing their potential for hands-on educational computing and laying groundwork for in classrooms. This initiative reflected his belief in accessible hardware as a tool for fostering problem-solving skills among students, predating widespread institutional adoption of personal computers in . By 1990, Wozniak began collaborating with the Los Gatos School District in , hiring teachers to deliver instruction to students, often in informal settings like his home. He formalized this support through district adoption, providing hardware and resources—including 11 modern computers by 1996—to enable practical tech literacy programs. These efforts prioritized direct student engagement over theoretical curricula, aligning with Wozniak's engineering-first approach to learning. In October 2017, Wozniak established Woz U, a postsecondary online training platform targeting skills gaps in technology fields such as , cybersecurity, and . The program features project-based modules designed for independent learners and corporate upskilling, with an initial app for career assessment to customize pathways. Woz U expanded to include K-12 elements under Woz ED, offering STEM career pathways from pre-K through grade 12 in areas like , coding, AI, and drones, serving multiple school districts and aligning with state standards for job-ready competencies. Wozniak personally oversees annual inductions for participating schools at the Woz ED Pathway Conference, ensuring continuity of his focus on curiosity-driven, practical education. Wozniak co-founded Woz U, an online technology education platform launched in 2017 aimed at providing affordable bootcamps in areas like cybersecurity, , and , with tuition around $13,200 for 33-week programs. Former students criticized the program's quality, reporting outdated pre-recorded lectures, frequent typos in materials, unresponsive mentors lacking expertise, and a lack of live instruction, leading some to describe it as equivalent to "a $13,000 e-book" with minimal value for job placement. Employees and participants also alleged aggressive sales practices, including high-pressure enrollment tactics and unfulfilled promises of personalized support, contributing to perceptions of the initiative as underdelivering relative to its branding tied to Wozniak's reputation. Woz U representatives responded by expressing disappointment in individual experiences but emphasized ongoing curriculum reviews by Wozniak and commitments to improvement without pressuring students. In May 2021, business professor Ralph Reilly filed a lawsuit against Wozniak and Woz U in federal court, accusing them of and theft by allegedly using Reilly's proposed concept for a Wozniak-branded tech school without permission or compensation after discussions in 2016. The court dismissed claims but allowed allegations to proceed initially; however, Wozniak prevailed fully by June 2021 when the case was resolved in his favor, with no admission of liability.

Intellectual Views and Commentary

Stances on Technological Innovation and Business Practices

Wozniak has consistently advocated for open-source principles in technological development, arguing that sharing designs and code fosters collaboration and accelerates innovation. In a 2017 keynote, he praised the maker movement for enabling individuals to build and experiment freely, contrasting it with closed systems that limit progress. He has emphasized that early personal computers like the Apple II succeeded partly because schematics and repair manuals were provided, embodying an "open source" ethos before the term was widespread. More recently, in 2025, Wozniak called for expanded open-source code to drive future tech advancements, warning that proprietary barriers hinder collective ingenuity. On hardware , Wozniak prioritizes simplicity and fun as core drivers, crediting his designs to playful problem-solving rather than market-driven mandates. He has critiqued large corporations for impeding through , stating in 2016 that big companies act as an " to " and that true breakthroughs come from young makers unburdened by corporate structures. This aligns with his early decision to publish the design in hobbyist magazines like Byte, allowing widespread replication and refinement by enthusiasts. Wozniak maintains that thrives when engineers focus on elegant, accessible solutions over hype, as evidenced by his reluctance to prioritize executive roles at Apple. Regarding business practices, Wozniak expresses skepticism toward profit-maximizing models that prioritize control over user , notably criticizing Apple's modern restrictions on device repairs. In 2021 testimony, he argued that consumers deserve the "" their own hardware, pointing out that Apple's ecosystem exerts excessive control antithetical to the company's origins in open hardware. He has voiced disdain for money's corrupting influence, avoiding investments and stating in that proximity to risks distorting values—a he demonstrated by offering $10 million in Apple stock to early customers during the 1980 IPO. Wozniak favors lean, engineer-led ventures over scaled enterprises, believing the latter dilute the purity of with demands.

Positions on Artificial Intelligence and Safety

Steve Wozniak has expressed a generally optimistic outlook on as a tool that enhances human capabilities without diminishing individual agency, while advocating for caution regarding its advanced development and potential misuse. In a February 2024 discussion at , he described AI as "just another one of these many steps" in technological progress, emphasizing that it integrates into daily life without eroding human value. He has praised early implementations, such as Apple's AI features announced in June 2024, noting that initial Siri interactions "worked fine" but requiring further evaluation for reliability. In November 2024, Wozniak quipped a preference for "Actual Intelligence" over AI in critiquing overhyped features like Apple Intelligence, underscoring his view that intuitive, remains paramount in technology. On , Wozniak has highlighted immediate risks from current systems, particularly their exploitation in and . In May 2023, he warned that advancing AI tools like enable sophisticated scams, deepfakes, and campaigns, predicting a surge in online weaponization that could erode trust in digital interactions. He argued that halting AI development entirely is infeasible, instead urging enhanced public education to detect such threats, as individuals must adapt to discern AI-generated falsehoods. Wozniak's concerns intensify with superintelligent AI, where he supports stringent regulatory pauses. On October 22, 2025, he joined over 800 signatories—including figures like and diverse voices from tech, , and —in an demanding an interim global on developing AI systems surpassing human-level intelligence across all domains until broad confirms their safety and alignment with human interests. The statement cites risks to , civil liberties, human dignity, and control, positing that unchecked pursuit of could lead to irreversible harms without verifiable safeguards. This stance aligns with his broader emphasis on responsible innovation, drawing from first-hand experience in computing's evolution to prioritize human-centric outcomes over unchecked advancement.

Opinions on Politics, Government, and Tech Influence

Wozniak has articulated libertarian-leaning perspectives, emphasizing individual freedoms and skepticism toward overreach in technological domains. In a 2012 interview, he opposed U.S. efforts to curb through like SOPA, arguing that such interventions infringe on personal liberties and fail to address root causes effectively. His stance reflects a preference for market-driven solutions over regulatory mandates, consistent with his early advocacy for in computing. Regarding encryption and privacy, Wozniak firmly supported Apple during the dispute with the FBI over unlocking an from the San Bernardino shooting case, deeming the agency's demands "just wrong" and the chosen case "lame" due to its limited evidentiary value. He argued that mandating backdoors would compromise universal device security without deterring criminals, who could access alternative encrypted tools, prioritizing and over selective law enforcement access. On cryptocurrency, Wozniak has warned that governments inherently seek to retain control, predicting resistance to decentralized systems despite their mathematical integrity, as stated in a 2021 interview where he noted, "the government will never allow it to be out of their control." This view extends to broader regulatory skepticism, including criticism of the FCC's understanding of internet dynamics in 2017 and advocacy for a "free" internet in 2010, cautioning that government agencies rarely align with public interests. Wozniak has critiqued the increasing entanglement of leaders with , asserting in March 2025 that skills for political differ fundamentally from those in tech innovation, and that massive firms should influence policy via rather than direct roles. He specifically opposed Elon Musk's leadership of the Department of Government Efficiency (DOGE), labeling mass federal job cuts a "sledgehammer" tactic unsuited to thoughtful administration. Earlier, in 2016, he expressed strong personal revulsion toward , stating the presidential candidate made him "cry out loud." Federal campaign finance records indicate Wozniak has made donations to political candidates and parties, including contributions in as Apple co-founder, though specific recipients and amounts vary by cycle and do not indicate strict partisan allegiance. His commentary consistently prioritizes technological autonomy and minimal state interference, viewing excessive political involvement by tech elites as a of both spheres.

Personal Life

Wozniak married Alice Louise Robertson in 1976 shortly after the founding of Apple Computer; the union lasted four years and ended in divorce in 1980, with Robertson receiving one-third of Wozniak's Apple stock as part of the settlement. No children resulted from this marriage. His second marriage was to on June 13, 1981; they had three children—Jesse John Wozniak, Sara Nadine Wozniak, and Stephen Gary Wozniak Jr.—before divorcing in 1987, with the youngest child born after the divorce was finalized. Wozniak wed Suzanne Mulkern, a high school acquaintance and mother of three from a prior relationship, in 1990; they divorced in 2004 after 14 years, producing no additional children. In 2008, he married Janet Hill, his fourth wife, with whom he resides in Los Gatos, California. Prior to this, Wozniak briefly dated comedian Kathy Griffin in 2007–2008, a relationship documented in Griffin's reality series My Life on the D-List but which ended amicably without leading to marriage.

Health Incidents and Recovery

In February 1981, Wozniak piloted a A36 that crashed shortly after takeoff from a private airstrip in , due to improper loading and mechanical issues. The accident resulted in severe head trauma and , leading to that prevented him from forming new long-term memories for approximately five weeks. He spent much of his initial recovery period in the hospital and at home, engaging in activities like watching movies to pass time, until his memory function returned abruptly during a phone call. Wozniak's full recovery from the crash injuries extended over two years, during which he dealt with lingering effects of the brain injury while stepping back from Apple to focus on personal healing. In 1982, he re-enrolled at the , under the pseudonym "Berkeley" to complete his bachelor's degree in and , which he finished in 1986. This period marked a deliberate low-profile phase, allowing him to regain cognitive stability without public pressure, though he later reflected that the oddly reinforced his prior knowledge of the computer design. On November 8, 2023, while attending the World Business Forum in , Wozniak experienced sudden dizziness and vertigo that left him unable to walk, prompting hospitalization where an MRI confirmed a minor ischemic accompanied by a small leak. He was discharged within days and returned to the by flight, reporting to media outlets that he was "doing good" and prioritizing further medical evaluation at home. By November 10, 2023, Wozniak stated he was feeling positive about his condition, with no indications of long-term impairments disclosed publicly.

Lifestyle, Hobbies, and Relocation

Wozniak primarily resides in , having maintained homes in the for much of his life, including a custom-designed modern residence completed in 1986 and a subsequent move to a new property on Blackberry Hill Road in 2003.
