Josephine Cochran (later Cochrane; née Garis; March 8, 1839 – August 3, 1913) was an American inventor[1] who invented the first successful hand-powered dishwasher, which she designed and then constructed with the assistance of mechanic George Butters, who became one of her first employees.[2][3]

Key Information

Once her patent issued on 28 December 1886, she founded Garis-Cochrane Manufacturing Company to manufacture her machines. Cochrane showed her new machine at the World's Columbian Exposition in Chicago in 1893 where nine Garis-Cochran washers were installed in the restaurants and pavilions of the fair and was met with interest from restaurants and hotels, where hot water access was not an issue. She won the prize for "best mechanical construction, durability and adaptation to its line of work" at the Fair. Garis-Cochran Manufacturing Company, which built dishwashers, grew through a focus on hotels and other commercial customers and was renamed as Cochran's Crescent Washing Machine Company in 1897.[4]

Cochran's Crescent Washing Machine Company became part of KitchenAid through acquisition by Hobart Manufacturing Company several years after Cochran's death in 1913.[5] Cochran was posthumously inducted into the National Inventors Hall of Fame in 2006 for patent 355,139 issued on December 28, 1886, for her invention of the dishwasher.[6]

Biography

[edit]
Portrait of Josephine Garis Cochrane as a young woman.

She was born Josephine Garis in Ashtabula County, Ohio, on March 8, 1839, and raised in Valparaiso, Indiana. She was the daughter of John Garis, a civil engineer, and Irene Fitch Garis, as well as the granddaughter of an innovator.[7]

After moving to her sister's home in Shelbyville, Illinois, she married William Cochran (later Cochrane) on October 13, 1858. William had returned the year before from a disappointing try at the California Gold Rush but had gone on to become a prosperous dry goods merchant and Democratic Party politician. She took her husband's name but spelt it with an "e" on the end.[8] Josephine and William had 2 children: Hallie and Katharine.[9]

In 1870, the family moved into a mansion, and Cochrane joined Chicago society. After one dinner party, some of the heirloom dishes got chipped while being washed, prompting her to search for a better alternative to handwashing.[10] She also wanted to relieve tired housewives from the duty of washing dishes after a meal.[11]

Cochrane’s dishwasher

[edit]

Other attempts had been made to produce a commercially viable dishwasher. In 1850 Joel Houghton designed a hand-cranked dish soaker,[12] In the 1860s, L.A. Alexander improved on the device with a geared mechanism that allowed the user to spin racked dishes through a tub of water. Neither of these devices was particularly effective.[13] Josephine Cochrane's invention of the dishwashing machine eventually became a success. However, this not only took a great deal of time and effort, but she also faced numerous obstacles in her journey to becoming a successful female innovator. Following the death of her husband in 1883, Cochrane was left with only $1,535.59 (about the equivalent of $47,000USD today[14]) and a significant amount of debt, which she had to pay off.[15]

After filing her first patent application on December 31, 1885, she began developing a prototype of her product.[7] Cochrane designed the first model of her dishwasher in the shed behind her house in Shelbyville, Illinois.[16] George Butters was a mechanic who assisted her in the construction of the dishwasher. He was also an employee at the first dishwasher factory. To build the machine, she first measured the dishes and built wire compartments, each specially designed to fit either plates, cups, or saucers. The compartments were placed inside a wheel that lay flat inside a copper boiler. A motor turned the wheel while hot soapy water squirted up from the bottom of the boiler and rained down on the dishes. Their dishwasher was the first to use water pressure instead of scrubbers to clean the dishes inside the machine.[17] She received a patent on December 28, 1886.[citation needed]

An improved model from 1914, US Patent 1,223,380.

Another challenge she faced was selling her product to individual households, specifically housewives. The first dishwashers were too expensive for an average household, costing between $75 and $100, which most women would not spend on an item for their kitchen even if it meant easing the effort they had to put in washing dishes.[7] In addition, most homes in that era were not equipped to handle the machine's requirements for hot water.[18] However, years later,[when?] homes began adding boilers that were big enough to meet those requirements, eventually allowing Cochrane to sell to housewives.[citation needed]

The World's Columbian Exposition in 1893 was pivotal in Cochrane's business as other companies relying heavily on investors were wiped out the same year in the Panic of 1893.[clarification needed] Following the exposition, many restaurants and hotels placed orders (with colleges and hospitals delayed in following due to sanitation requirements). In 1898, she opened her own factory with George Butters as manager so she could extend her sales north and south, reaching from Mexico to Alaska.[citation needed]

Her main customers continued to be hotels and restaurants. It was not until the 1950s that dishwashers became popular for home usage. Cochrane died in 1913 at 74. In 1926, her company was sold to KitchenAid, now part of Whirlpool Corporation.[5]

Death and recognition

[edit]

Cochrane died of a stroke or exhaustion in Chicago, Illinois, on August 3, 1913, aged 74, and was buried in Glenwood Cemetery in Shelbyville, Illinois.[19] In 2006, she was inducted into the National Inventors Hall of Fame.[20]

Josephine Garis Cochrane (March 8, 1839 – August 3, 1913) was an American inventor, entrepreneur, and socialite renowned for developing the first commercially successful automatic , a device that revolutionized kitchen labor by using water pressure to clean dishes without manual scrubbing. Born in , to a family with engineering ties—her great-grandfather John Fitch was an early pioneer—Cochrane grew up in a privileged environment but faced financial challenges after her husband William Apperson Cochran's death in 1883, prompting her to pursue to protect her from servants' breakage during hand-washing. Lacking formal engineering training, she designed her machine with the help of mechanic George Butters, featuring wire racks to hold dishes in a copper boiler where targeted water jets cleaned them, and filed for U.S. Patent No. 355,139 on December 31, 1885, which was granted on December 28, 1886. Cochrane founded the Garis-Cochran Manufacturing Company in , to produce and market her , initially targeting commercial users like hotels, restaurants, and hospitals where it could wash up to 240 dishes in two minutes, though early models required hand-cranking and hot boiler water. Her breakthrough came at the 1893 in , where the won the highest award for mechanical construction, boosting sales and leading her to relocate the business there in 1890. Over her career, Cochrane secured six U.S. patents and two British ones related to dishwashing improvements, demonstrating her persistence as one of the few women inventors of the to achieve commercial success in a male-dominated field. After her death from a in , her company evolved through mergers—becoming Cochran's Crescent Company around 1898, then acquired by Manufacturing in 1926 and in 1986—ultimately birthing the brand, which popularized electric dishwashers in American homes by the 1950s. Inducted into the in 2006, Cochrane's legacy endures as a pioneer who transformed domestic chores into efficient, mechanized processes.

Early Life

Family Background

Josephine Garis Cochrane was born on March 8, 1839, in , to John Garis, a prosperous , and Irene Fitch Garis. Her father was known for his work in engineering, supervising woolen mills, sawmills, and gristmills along the , as well as contributing to infrastructure development in the Midwest. Irene Garis came from a family with roots in early American history. Cochrane was often described in press accounts as a descendant of the inventor John Fitch, a Revolutionary War veteran who received the first U.S. for a in 1791; however, family research confirmed no close relation, though she promoted the connection for publicity purposes. Raised primarily in , due to her father's career moves, Cochrane gained informal exposure to principles through his professional endeavors across , , and . Lacking formal mechanical education—uncommon for women of her era—she absorbed practical knowledge at home, observing and assisting with her father's tools and projects, which fostered her innate mechanical aptitude. Brought up in a prominent, affluent family that relocated frequently, Cochrane enjoyed socioeconomic stability in the Midwest's developing industrial landscape, allowing early immersion in concepts without formal schooling.

Marriage and Family

At the age of 19, Josephine Garis married William Apperson Cochran on October 13, 1858, in , where the couple established their home. William was a prosperous merchant who later served as Circuit Clerk of Shelby County. Upon taking her husband's surname, she added an "e" to spell it Cochrane, believing the alteration lent a more distinguished air. The marriage produced two children: a son, Hallie, who died at age two, and a , Katharine. The family led a comfortable existence in Shelbyville, with Cochrane hosting frequent dinner parties that showcased her collection of heirloom china, supported by household servants. William's business fortunes declined due to unsuccessful investments and his battle with , culminating in his death on October 20, 1883. He left Cochrane a at 44, with just $1,500 in assets against mounting debts that forced her toward and self-determination.

Invention of the Dishwasher

Motivation and Development

In the early , Josephine Cochrane grew increasingly frustrated with the damage inflicted on her by household servants during manual dishwashing, as the fragile heirlooms—some dating back centuries—frequently chipped or broke under rough handling. This personal irritation, compounded by the tedious nature of the task when she attempted it herself, prompted her to begin sketching preliminary designs for an automated cleaning device around 1883. Facing financial urgency after her husband's death in 1883 left her in debt, Cochrane made a determined vow: "If nobody else is going to invent a dishwashing machine, I’ll do it myself." She established a makeshift workspace in the shed behind her home in , where she refined her concepts independently at first. To bring her vision to life, Cochrane collaborated with local mechanic George Butters, enlisting his expertise to construct the initial prototype in the mid-1880s. The device featured wire racks customized to securely hold dishes—such as plates, saucers, and teacups—in a , with high-pressure water jets propelled by pumps to clean without direct scrubbing. Early testing revealed significant hurdles, including leaks in the rudimentary plumbing and the need for iterative adjustments to the wire compartments to prevent damage to delicate items like teacups during the forceful water sprays. Cochrane also encountered resistance from male assistants who were skeptical of her unconventional methods, leading to trial-and-error refinements that increased development costs but ultimately improved the machine's reliability for fragile china.

Patent and Design

On December 28, 1886, Josephine Cochrane was granted U.S. No. 355,139 for her "Dish-Washing Machine," which described a mechanical device utilizing a rotating to hold dishes while subjecting them to streams of soapy water or rinse water under pressure. The patent outlined a system where dishes were secured in wire frames or baskets within the reel, ensuring they remained stationary relative to each other to avoid chipping during the washing process. This design emphasized mechanical simplicity, with the reel rotating to allow for operation. The core mechanism featured cylindrical wire cages for plates and saucers, along with adjustable racks for larger items such as cups and bowls, all arranged within a rectangular frame equipped with a hinged lid for secure containment. A geared wheel system, including a beveled pinion and gear on the driving shaft, facilitated the reel's rotation, powered initially by a hand crank for accessibility to non-experts. Water delivery was achieved through eduction pipes fitted with fan-shaped nozzles, which directed pressurized jets lengthwise across the reel to ensure comprehensive coverage without manual scrubbing. The patent diagrams illustrated this setup, showing the reel's position within a wooden enclosure connected to water chambers for soap-suds and rinsing, with a tilting deflector to manage flow between cycles. Key innovations in the included reliance on water pressure from a or system to clean dishes, eliminating the need for scrubbing and reducing wear on fragile . Separate compartments within the dual-reel configuration prevented dishes from colliding, addressing common breakage issues in manual , while the wire allowed for various dish sizes through customizable baskets. These elements marked a shift toward efficient, damage-free in household appliances. Cochrane secured five additional U.S. patents and two British patents between and , for a total of six U.S. patents, focusing on enhancements such as improved rotary sprayers for better water distribution and reinforced components for increased durability. For instance, her 1911 U.S. No. 1,009,223 introduced refinements to the washing mechanism for more uniform cleaning. These filings built upon the original design, extending its practical application in commercial settings.

Business Ventures

Company Formation

Following the issuance of her U.S. No. 355,139 on December 28, 1886, Josephine Cochrane established the Garis-Cochran Manufacturing Company in , to manufacture and sell her newly invented dishwasher. The company's name combined Cochrane's maiden name, Garis, with her married surname, reflecting her personal stake in the venture. The initial funding came primarily from Cochrane's personal savings, accumulated after her husband's death in 1883 left her in financial straits. Limited resources constrained early operations to hand-built units, produced in a modest workshop that relied on local workers for assembly and support. Cochrane assumed the role of company president, personally directing refinements and overseeing production to ensure aligned with her original vision. In , she opened her own in Shelbyville with George Butters as manager and renamed the firm the Cochran's Washing Machine Company.

Commercialization and Challenges

Cochrane achieved her first commercial sale in 1887 to the Palmer House Hotel in . She later secured an $800 order from the Sherman House Hotel in . Recognizing that the high installation costs and inadequate residential water supplies made the impractical for most households, she strategically targeted large institutions such as hotels, restaurants, and hospitals, where greater volumes of were needed and supported the machine's operation. A significant boost to commercialization came with the demonstration of her at the 1893 in , where the machine showcased its efficiency by cleaning 240 dishes in two minutes. Nine units were installed in the exposition's restaurants, providing practical validation of the 's reliability. The earned the highest honor at the event—a prize for "best mechanical construction, durability, and adaptation to its line of work"—which enhanced its credibility and attracted institutional interest. Despite these successes, Cochrane faced substantial challenges in promoting her product. The machines were priced between $75 and $800 per unit, rendering them unaffordable for the average homemaker and limiting early adoption in private homes. Skepticism among domestic users stemmed from entrenched preferences for hand-washing and doubts about the machine's ability to clean without damaging delicate . Additionally, plumbing limitations in 1890s residences, including insufficient hot water capacity, hindered residential viability. As a inventor operating in a male-dominated sector, Cochrane encountered gender bias, including resistance from male investors and factory managers who questioned her expertise and sought to impose traditional methods, often leading to production setbacks. In response to these barriers, Cochrane pivoted decisively toward commercial markets, focusing sales efforts on institutions that could justify the . By the early , this strategy yielded steady sales to hotels, restaurants, and hospitals across the and even internationally, such as in and , establishing a reliable revenue stream and laying the groundwork for broader industry adoption.

Later Life

Relocation and Continued Work

In 1890, following the death of her husband in 1883 which left her in significant debt, Josephine Cochrane relocated from , to to capitalize on the city's burgeoning commercial markets for her and to access superior manufacturing resources. This move positioned her closer to major hotels and restaurants, key early customers for her , and allowed her to expand operations amid the industrial growth of the late . Cochrane took an active role in managing her company, initially the Garis-Cochran Manufacturing Company (renamed Cochran's Crescent Company around 1898), overseeing production expansions that included opening a factory in around 1898 to meet increasing demand from commercial clients. She continued refining her design, filing multiple additional patents—ultimately securing six U.S. and two British patents by 1913—for improvements such as enhanced water circulation systems in the early , which optimized cleaning efficiency and durability. These innovations helped sustain the company's growth, focusing on robust machines suited for high-volume use in institutions rather than households. Her involvement in preparations for the 1893 in marked a pivotal moment, where she demonstrated her to thousands of visitors, securing the highest for mechanical , durability, and to its purpose. This exposure elevated her profile as an inventor-entrepreneur, leading to increased orders and recognition within industrial circles. Throughout this period, Cochrane resided in a prominent home, balancing social engagements in elite society with her primary focus on business leadership and innovation.

Josephine Cochrane's invention of the marked a pivotal shift in household appliance technology by introducing a mechanized process that relied on pressurized jets to scrub dishes without manual intervention. Her 1886 featured a wire rack system and water pressure mechanism that protected fragile while effectively removing residue, a foundational approach that persisted despite subsequent innovations. Initially hand-cranked, the design evolved in the with the integration of electric motors, transitioning from manual operation to powered automation and enabling broader domestic use. This core water-pressure jet system remains integral to contemporary , which continue to employ rotating sprayers and recirculated for efficient cycles. The trajectory of Cochrane's company further amplified her technological influence. In 1926, her Crescent Washing Machine Company was acquired by the Hobart Manufacturing Company, which rebranded the product line as and expanded production of electric models for both commercial and home markets. This acquisition facilitated mass manufacturing and innovation, culminating in KitchenAid's acquisition by the in 1986, which accelerated the appliance's integration into mid-20th-century households during the post-World War II boom in . By the , advancements in materials, detergents, and energy efficiency—building on Cochrane's framework—drove widespread adoption, transforming dishwashers from institutional tools to standard kitchen fixtures. Cochrane's dishwasher had profound broader effects on technology and society, significantly reducing the physical labor associated with in homes and institutions, where manual cleaning previously consumed hours daily. This labor-saving innovation paved the way for a wave of automated appliances, including electric washers and food processors, by demonstrating the feasibility of mechanizing domestic chores and freeing time, particularly for women confined to traditional roles. In commercial settings like restaurants and hotels, it streamlined operations, influencing the development of durable, high-capacity models that supported the growth of the food service industry. Today, the enduring relevance of Cochrane's design is evident in its efficiency roots, with over 70% of U.S. households owning dishwashers as of 2024, reflecting a penetration rate that underscores the appliance's evolution into energy-efficient, smart-enabled devices. This high adoption rate traces back to her pioneering water-jet technology, which continues to underpin modern systems despite additions like sensors and app connectivity.
