Wilson Greatbatch (September 6, 1919 – September 27, 2011) was an American engineer and pioneering inventor. He held more than 325 patents and was a member of the National Inventors Hall of Fame and a recipient of the Lemelson–MIT Prize[1] and the National Medal of Technology and Innovation (1990).

Key Information

Early years

[edit]

Greatbatch was born in Buffalo, New York and attended public grade school at West Seneca High School.[2][3] He entered military service and served during World War II, becoming an aviation chief radioman before receiving an honorable discharge in 1945.[3] He attended Cornell University as part of the GI Bill, graduating with a B.E.E. in electrical engineering in 1950; he received a master's degree from the University of Buffalo in 1957. Wilson loved fiddling with objects and this would lead to great things.[3]

The Chardack-Greatbatch pacemaker

[edit]

The Chardack-Greatbatch pacemaker used Mallory mercuric oxide-zinc cells (mercury battery) for its energy source, driving a two transistor, transformer coupled blocking oscillator circuit, all encapsulated in epoxy resin, then coupled to electrodes placed into the myocardium of the patient's heart. This patented innovation led to the Medtronic company of Minneapolis commencing manufacture and further development of artificial cardiac pacemakers.[4]

The Greatbatch lithium-iodide battery cell

[edit]

In 1968, Catalyst Research Corporation of Baltimore, Maryland developed and patented a lithium battery cell U.S. patent 4,049,890. The cell used two elements at near ends of the electrochemical scale, causing a high voltage of 2.8V and an energy density near the physical maximum. Unfortunately, it had an internal impedance which limited its current load to under 0.1 mA and was thus considered useless.

Greatbatch sought to introduce this invention into the pacemaker industry, which could readily use a high impedance battery. The early work was conducted in a rented area of the former Wurlitzer Organ Factory in North Tonawanda, New York. Ralph Mead is understood to have headed the early electrochemical development.

Greatbatch introduced the developed WG1 cell to pacemaker developers in 1971, and was met with limited enthusiasm. On July 9, 1974, Manuel A. Villafaña and Anthony Adducci founders of Cardiac Pacemakers Inc.(Guidant) in St. Paul, Minnesota, manufactured the world's first pacemaker with a lithium anode and a lithium-iodide electrolyte solid-state battery.[5][6] The lithium-iodide cell manufactured by Greatbatch is now the standard cell for pacemakers, having the energy density, low self-discharge, small size and reliability needed.

In the cell as developed for cardiac pacemaker application, the anode is lithium and the cathode a proprietary composition of iodine and poly-2-vinylpyridine, neither of which is electrically conductive. However, after processing by mixing and heating to ~ 150 °C for 72 hours the components react with each other to form an electrically conductive viscous liquid which, while still molten, is poured into the cell where it cools to form a solid. When the liquid contacts the lithium anode it creates a monomolecular layer of semiconducting crystalline lithium iodide. As the cell is discharged by the current load of the pacemaker, the reaction between the lithium anode and iodine cathode forms a growing barrier of lithium iodide, This is resistive, and causes the terminal voltage of the cell to decrease approximately as an inverse function of the volume of the barrier. Pacemaker designers use this characteristic to permit detection of incipient 'end of life' of the pacemaker's lithium cell.

Philanthropy

[edit]

Greatbatch donated funds to Houghton College in New York to create a graduate program in music. The Houghton College Center for the Arts (CFA) was designed with his donations to include a concert hall, art gallery, multi-floor gathering space, and various choir and instrumental practice rooms. It was subsequently named the Greatbatch School of Music after him. Houghton College assisted Greatbatch in his research, when he was unable to generate support, providing him with lab space and research assistance.[7]

In 2009, Wilson and Eleanor Greatbatch donated approximately $10 million to create a modern glass reception and interpretive pavilion, called the Eleanor and Wilson Greatbatch Pavilion, separate from the Darwin D. Martin House Complex. It was designed by Toshiko Mori, chair of the department of architecture at Harvard's Graduate School of Design.[8]

Death

[edit]

Wilson Greatbatch died at the age of 92 on September 27, 2011.[9][10] Greatbatch served as an elder at Clarence Presbyterian Church, where he also sang in the church choir and taught Sunday school.[11]

Wilson Greatbatch (September 6, 1919 – September 27, 2011) was an American electrical engineer and prolific inventor renowned for developing the first successful implantable cardiac pacemaker in 1958, a groundbreaking that revolutionized treatment for heart rhythm disorders and has saved millions of lives worldwide. Born in , Greatbatch served in the U.S. Navy from 1936 to 1945, including during , where he worked as an aviation chief radioman before pursuing higher education. He earned a Bachelor of Electrical Engineering from in 1950 and a master's degree from the at Buffalo in 1957, later becoming an of engineering at the university. Greatbatch's pivotal invention occurred serendipitously in 1958 while he was building an oscillator to record heart sounds at the University of Buffalo; he accidentally installed a 1 MΩ resistor instead of a 10 KΩ one, resulting in a circuit that produced a steady 1.8-millisecond pulse every second, mimicking a heartbeat. Collaborating with surgeons Dr. William Chardack and Dr. Andrew Gage at the Buffalo Veterans Affairs Hospital, he refined the device over two years, including through animal testing beginning with the first successful implant in a dog on May 7, 1958. The inaugural human implantation took place in 1960 on a 77-year-old patient, who survived for two years, followed by reports of 15 successful human implants by 1961; Greatbatch secured U.S. Patent No. 3,057,356 for the implantable pacemaker. In the 1970s, Greatbatch advanced pacemaker technology further by developing the lithium-iodide battery for pacemaker use, which extended device longevity to over 10 years and became a standard in the field. In 1970, he founded Greatbatch, Inc. (later acquired and renamed Integer Holdings Corporation), initially to produce these long-life primary batteries for pacemakers and other medical devices. Throughout his career, he amassed over 325 patents, spanning medical electronics, environmental innovations like a solar-powered canoe, and even research into AIDS treatments. Greatbatch received numerous accolades for his contributions, including induction into the in 1986, the National Medal of Technology in 1995, and the Lemelson-MIT Lifetime Achievement Award; in 1983, the National Society of Professional Engineers named his pacemaker one of the top two achievements of the previous half-century. His work not only transformed cardiac care—leading to tens of millions of pacemaker implants globally since 1960—but also exemplified interdisciplinary innovation at the intersection of and .

Early Life and Education

Childhood and Family Background

Wilson Greatbatch was born on September 6, 1919, in , to a working-class family. His father, Warren Greatbatch, was an immigrant who had worked as a green grocer in before becoming a carpenter and building contractor in the United States after arriving around 1900. Greatbatch's mother, Charlotte Margaret Recktenwalt Greatbatch, was American and met his father through a local society in Buffalo, where both participated; they married around the time of . The family dynamics played a key role in fostering Greatbatch's early curiosity about and problem-solving. His father's trade as a carpenter exposed him to hands-on work with tools and materials from a young age, while his mother's encouragement emphasized resourcefulness, often advising that "there is always a way" to address challenges. As the only child in the household—though he had a half-brother from his father's previous who had died by then—Greatbatch grew up on Buffalo's south side in the West Seneca suburb, where the working-class environment instilled a practical, inventive mindset. Greatbatch attended West Seneca High School, where his interests in electronics began to emerge prominently. As a youngster, he developed a passion for radio technology, tinkering with components and building devices; by around 1936, as a member of the , he constructed a radio transmitter that aided in hurricane relief efforts, earning him a Red Cross citation for his contributions. Greatbatch's early life unfolded amid the , which began when he was about 10 years old, amplifying the family's modest circumstances and promoting through resourceful fixing and building around the home. These formative experiences in Buffalo's industrial setting laid the groundwork for his lifelong pursuit of engineering innovation.

Military Service and Higher Education

During , Wilson Greatbatch served in the U.S. Navy, initially joining the Naval Reserve in 1938 before entering active duty in 1940 as a radioman third class. He advanced to the rank of aviation chief radioman, receiving an honorable discharge in 1945 after contributing to both Atlantic and Pacific theater operations. His early interest in radio, sparked by family tinkering with , provided a strong foundation for his technical aptitude in the service. Greatbatch gained extensive hands-on experience with and , including roles in and operation. He trained at a school in and later instructed at Navy radar and radio schools, such as setting up a program at Annapolis and teaching at . During patrols, he flew PBY aircraft on 13-hour missions along the coastline to detect German submarines using early systems, and he served in a dive-bombing squadron aboard the USS Monterey , where he maintained and operated radio and equipment essential for and . These experiences honed his skills in complex electronic systems under demanding conditions, fostering the discipline that would later define his engineering innovations. Following the war, Greatbatch utilized the to pursue higher education, enrolling at to study . He earned a (B.E.E.) degree in 1950, focusing on communications with an emphasis on . He then advanced his studies at the (now SUNY Buffalo), completing a in in 1957. This graduate work deepened his expertise in research-oriented electrical systems, preparing him for academic and professional roles in engineering.

Professional Career Beginnings

Early Engineering Work

After graduating from with a in 1950, Greatbatch began his professional career in roles that emphasized practical applications in and . He initially worked at 's Psychology Department animal behavior farm, where he designed and built amplifiers to monitor heart rates and in sheep and goats, gaining early experience with biological signal recording. This role, starting around 1951, involved attaching instruments to over 100 animals and laid foundational skills in audio electronics for physiological data. He also contributed to 's radio astronomy efforts by constructing receivers for the in , honing his expertise in high-fidelity amplification systems. In 1952, while pursuing a master's degree at the University of Buffalo, Greatbatch joined the university as an in the department, where he taught and conducted research at the Chronic Disease . By 1957, after completing his M.S., he transitioned to industry as manager of the division at Taber Instrument Corporation, a local Buffalo firm specializing in precision instruments. At Taber, he oversaw development of electronic components but encountered resistance when proposing biomedical projects, as the company prioritized commercial applications over experimental medical work. These positions in Buffalo-area institutions and firms built his proficiency in transistor-based circuits, drawing on his Cornell education to bridge general with emerging physiological monitoring needs. During the mid-1950s, Greatbatch pursued independent projects that foreshadowed his biomedical interests, including the design of compact audio recording devices to capture biological sounds such as heart rhythms. One such effort involved building an oscillator circuit using expensive silicon transistors—costing $90 each at the time—for recording rapid heartbeats in laboratory settings, which he developed in his spare time due to limited institutional resources. These solo endeavors, often conducted in makeshift workshops, highlighted his resourcefulness but also revealed funding challenges, as he relied on personal savings without dedicated grants or employer backing. Around 1956–1957, Greatbatch's independent work led to preliminary collaborations with medical professionals, beginning with informal discussions through the Professional Group on Medical Electronics and connections at the University of Buffalo. He met Dr. William Chardack, chief of at the Buffalo Veterans Administration , during this period, initiating joint explorations into electronic aids for cardiac monitoring amid skepticism from the medical community about implantable devices. Transitioning from general electronics to medical applications proved difficult, with early prototypes failing due to issues like inadequate sealing against body fluids and a lack of suitable power sources, compounded by the absence of venture funding in the nascent field. These hurdles forced Greatbatch to self-finance his experiments, investing about $2,000 from family savings while balancing full-time employment.

Research Collaborations in Buffalo

In 1958, Wilson Greatbatch, an assistant professor of at the , formed a pivotal partnership with Dr. William Chardack, chief of surgery at the Buffalo Veterans Administration Hospital (now the Buffalo VA Medical Center). This collaboration arose from Greatbatch's involvement in the local Professional Group on Medical Electronics and stemmed from his ongoing work on biomedical . Together, they initiated joint experiments focused on heart rhythm recording devices, aiming to develop tools for monitoring and potentially regulating cardiac activity in clinical settings. During these experiments, Greatbatch experienced a serendipitous breakthrough when he inadvertently installed a 1 MΩ instead of a 10 kΩ in an oscillator circuit designed for recording tachycardias. The resulting device produced electrical pulses of 1.8 milliseconds followed by a 1-second interval, closely mimicking the natural rhythm of a healthy heartbeat and suggesting potential for cardiac stimulation. This accidental discovery shifted their focus toward prototyping an implantable , with Chardack providing surgical expertise for design and implantation feasibility. Later in 1958, the team advanced to testing prototypes on dogs at the VA Hospital's animal laboratory, where they implanted electrodes connected to the external to evaluate pacing efficacy. Initial trials lasted about four hours but revealed challenges with device sealing against bodily fluids, which they addressed using encapsulation to improve reliability. These tests also highlighted the need to miniaturize the device and optimize power sources, as early mercury-zinc batteries limited longevity and the overall size was too bulky for practical human implantation. Concurrently, Greatbatch engaged in preliminary manufacturing discussions with , Inc., starting in late 1959, culminating in a licensing agreement in 1960 to produce units for human clinical trials.

Major Inventions in Biomedical Engineering

Invention of the Implantable Pacemaker

In 1958, while working as an instructor at the University of Buffalo, Wilson Greatbatch accidentally invented the core circuit for the implantable pacemaker during an attempt to develop a device for recording fast heart rhythms. Reaching into a parts box, he mistakenly installed a with 100 times the intended resistance—1 megohm instead of 10 kilohms—into a blocking-oscillator circuit powered by transistors. This error caused the circuit to produce self-interrupting pulses at a rate of 1.8 hertz, mimicking the rhythmic "lub-dub" of a natural heartbeat, which Greatbatch immediately recognized as suitable for cardiac stimulation. Greatbatch refined the design in collaboration with surgeon William Chardack at the Buffalo Veterans Administration Hospital, transitioning from external pacing prototypes to a fully implantable system. The resulting Chardack-Greatbatch pacemaker featured a compact using two transistors in a transformer-coupled blocking-oscillator configuration to deliver 100-microsecond pulses at 72 beats per minute. It was powered by a mercury-zinc battery from Mallory, expected to last approximately two years, and encapsulated in resin for and protection against bodily fluids, with the entire unit measuring about 5.5 by 4.5 by 1.5 centimeters and weighing 70 grams. Electrodes were sutured directly to the heart muscle via , enabling asynchronous ventricular pacing to treat and arrhythmias. After successful animal testing in dogs starting in May 1958, the device achieved its first implantation on June 6, 1960, in a 77-year-old patient with complete at Millard Fillmore Hospital in , performed by Chardack with assistance from surgeon Andrew Gage, in collaboration with the Buffalo VA Hospital. The patient survived for 18 months post-implant, demonstrating reliable function. That year, Chardack's team implanted pacemakers in a total of 10 patients, primarily elderly individuals with severe arrhythmias, marking the shift from bulky external units to practical internal therapy. , Inc., licensed the technology in late 1960 and began commercial production of the Model 5800, facilitating wider clinical adoption with dozens of implants by year's end. Greatbatch filed for a on July 22, 1960, which was granted as U.S. Patent 3,057,356 on October 9, 1962, covering the implantable cardiac pacemaker's circuit and assembly. Early clinical data showed restored effective heart rates, with survival post-implant often comparable to age-matched individuals without pacemakers, as it alleviated symptoms of and prevented sudden . By 1961, refinements included improved lead insulation and surgical techniques, solidifying the pacemaker's role in treating a range of arrhythmias and paving the way for tens of millions of implants worldwide since its introduction (as of 2025).

Development of the Lithium-Iodide Battery

In the late , early implantable pacemakers relied on mercury-zinc batteries that typically lasted only 2 to 3 years, often leading to , gas generation, and unpredictable failure, which necessitated frequent surgical replacements and increased patient risk. This limitation motivated engineers to seek a more reliable, longer-lasting power source that could enable a single lifetime implantation for most patients. Greatbatch addressed this challenge through collaboration with battery experts at Catalyst Research Corporation (CRC) in , , leading to the of the lithium-iodine battery in 1971. The design featured a , an iodine complexed with polyvinylpyridine to form a solid , and a solid , creating a fully solid-state system that avoided liquid components and enabled hermetic sealing. The electrochemical reaction powering the cell is simplified as: 2Li+I2→2LiI2\text{Li} + \text{I}_2 \rightarrow 2\text{LiI} This process releases energy with a nominal open-circuit voltage of approximately 2.8 V, free of gassing or corrosion products. The core technology was patented by CRC as U.S. Patent 4,049,890 in 1977, with inventors Ralph T. Mead, Frank W. Rudolph, and Norbert W. Frenz, covering the lithium-iodine cell structure and manufacturing method. Greatbatch's company licensed this patent and developed improvements, extending battery life to over 10 years in typical pacemaker applications by minimizing internal impedance and enhancing energy density. The lithium-iodine battery was first integrated into pacemakers by Cardiac Pacemakers, Inc. (CPI) in 1972, marking the inaugural clinical implantation of such a device and rapidly becoming the standard power source due to its reliability and longevity. As of 2025, it has powered tens of millions of implantable cardiac devices worldwide, with failure rates below 0.1% annually, and approximately 1.4 million pacemakers are implanted annually worldwide, the vast majority using this battery technology.
