==Early life and education==
Atanasoff was born on October 4, 1903, in [[Hamilton (village), New York|Hamilton, New York]] to an electrical engineer and a school teacher.<ref name="NYT"/> Atanasoff's father, Ivan Atanasov, was of [[Bulgarians|Bulgarian]] origin, born in 1876 in the village of [[Boyadzhik]], close to [[Yambol]], then in the [[Ottoman Empire]]. While Ivan Atanasov was still an infant, his own father was killed by Ottoman soldiers after the Bulgarian [[April Uprising]].((sfn|Atanasoff|1985)) In 1889, Ivan immigrated to the United States with his uncle. John's father later became an electrical engineer, whereas his mother, Iva Lucena Purdy (of mixed [[French Americans|French]] and [[Irish Americans|Irish]] ancestry), was a teacher of [[mathematics]].<ref>''The first electronic digital computer working on a binary code and using mathematical logic had been created in 1937-1942 by the American physicist of the Irish-Bulgarian origin John Vincent Atanasoff (1903-1995.)'' For more see: Mikhail Mikhailov (2005) Key to the Vedas, Belarusian Information Center, p. 62, ((ISBN|9856701872)).</ref><ref>''My mother (she is still alive, at 89 years of age) is a typical American with a mixture of Irish, English and French blood, so that the Bulgarian language was never spoken in our house''. For more see: [[Blagovest Sendov]] (2003) John Atanasoff: The Electronic Prometheus, St. Kliment Ohridski University Press, Sofia, p. 57, ((ISBN|954071849X)).</ref><ref>''During his variegated life, Atanasoff met and married a teacher of Mathematics, called Iva, with Irish and French blood in her veins. His wife bore eight children, one of whom was christened by his mother John – Vincent''. For more see: Dimitar Shishko (2001) John Atanasoff: The Father of the Computer, Tangra TanNakRa, p. 59, ((ISBN|9549942244)).</ref> 

Atanasoff was raised in [[Brewster, Florida]]. Young Atanasoff's ambitions and intellectual pursuits were in part influenced by his parents, whose interests in the natural and applied sciences cultivated in him a sense of critical curiosity and confidence.((citation needed|date=June 2021)) At the age of nine, he learned to use a [[slide rule]], followed shortly by the study of [[logarithm]]s, and subsequently completed high school at [[Mulberry High School (Mulberry, Florida)|Mulberry High School]] in two years.((citation needed|date=June 2021)) In 1925, Atanasoff received his Bachelor of Science degree in [[electrical engineering]] from the [[University of Florida]].<ref name="NYT"/>

He continued his education at [[Iowa State University|Iowa State College]] and in 1926 earned a [[master's degree]] in [[mathematics]].<ref name="NYT"/> He completed his formal education in 1930 by earning a [[PhD]] in [[theoretical physics]] from the [[University of Wisconsin–Madison]] with his thesis, ''The Dielectric Constant of Helium''.<ref name="NYT"/> Upon completion of his doctorate, Atanasoff accepted an assistant [[professor]]ship at Iowa State College in mathematics and [[physics]].((citation needed|date=June 2021))

==Computer development==
((see also|History of computing hardware))((Unreferenced section|date=June 2021))
[[Image:Atanasoff-Berry Computer.jpg|thumb|1997 replica of the Atanasoff–Berry Computer at [[Buildings of Iowa State University#D|Durham Center]], Iowa State University]]
Partly due to the drudgery of using the mechanical [[Monroe calculator]], which was the best tool available to him while he was writing his doctoral thesis, Atanasoff began to search for faster methods of computation. At Iowa State, Atanasoff researched the use of [[master/slave (technology)|slaved]] Monroe calculators and [[IBM]] [[Unit record equipment|tabulators]] for scientific problems, with which controlled the Monroe using the output of an IBM. In 1936 he invented an [[Analog computer|analog calculator]] for analyzing surface geometry. At this point, he was pushing the boundaries of what gears could do and the fine mechanical tolerance required for good accuracy pushed him to consider digital solutions.

With a grant of $650 received in September 1939 and the assistance of his graduate student [[Clifford Berry]], the [[Atanasoff–Berry Computer]] (ABC) was prototyped by November of that year. According to Atanasoff, several operative principles of the ABC were conceived by him during the winter of 1938 after a drive to [[Rock Island, Illinois]].

The key ideas employed in the ABC included [[Binary numeral system|binary]] math and [[Boolean logic]] to solve up to 29 [[simultaneous linear equations]]. The ABC had no [[central processing unit]] (CPU), but was designed as an electronic device using [[vacuum tube]]s for digital computation. It also had regenerative [[capacitor]] memory that operated by a process similar to that used today in [[DRAM]] memory.

==Patent dispute==
((details|Honeywell v. Sperry Rand))

Atanasoff first met [[John Mauchly]] at the December 1940 meeting of the [[American Association for the Advancement of Science]] in Philadelphia, where Mauchly was demonstrating his "harmonic analyzer", an analog calculator for analysis of weather data. Atanasoff told Mauchly about his new digital device and invited him to see it.((citation needed|date=June 2021))

In June 1941 Mauchly visited Atanasoff in [[Ames, Iowa]] for four days, staying as his houseguest. Atanasoff and Mauchly discussed the prototype ABC, examined it, and reviewed Atanasoff's design manuscript.((citation needed|date=June 2021)) In 1941 Atanasoff left Iowa State for a wartime assignment as Chief of the Acoustic Division with the [[Naval Ordnance Laboratory]] (NOL) in Washington, D.C.<ref name="NYT"/> No patent application for the ABC was subsequently filed by Iowa State College.((citation needed|date=June 2021))

Mauchly visited Atanasoff multiple times in Washington during 1943 and discussed computing theories, but did not mention that he was working on a computer project himself until early 1944.((sfn|Mollenhoff|1988|page=62–66))

By 1945 the [[United States Navy|U.S. Navy]] had decided to build a large-scale computer, on the advice of [[John von Neumann]]. Atanasoff was put in charge of the project, and he asked Mauchly to help with job descriptions for the necessary staff.((citation needed|date=June 2021)) However, Atanasoff was also given the responsibility of designing acoustic systems for monitoring [[atomic bomb]] tests.((citation needed|date=June 2021)) That job was made the priority, and he participated in the testing at [[Bikini Atoll]] in July 1946.<ref name="NYT"/> By the time he returned from the testing the NOL computer project was shut down due to lack of progress, again on the advice of von Neumann.((citation needed|date=June 2021))

In June 1954 IBM patent attorney A. J. Etienne sought Atanasoff's help in breaking an [[Eckert–Mauchly Computer Corporation|Eckert–Mauchly]] patent on a revolving magnetic memory drum, having been alerted by Clifford Berry that the ABC's revolving capacitor memory drum may have constituted [[prior art]]. Atanasoff agreed to assist the attorney, but IBM ultimately entered a patent-sharing agreement with [[Sperry Rand]], the owners of the Eckert–Mauchly memory patent, and the case was dropped.((sfn|Mollenhoff|1988|pages=81–86))

Atanasoff was deposed and testified at trial in the later action ''[[Honeywell v. Sperry Rand]]''. In that case's decision, Judge [[Earl R. Larson]] found that "Eckert and Mauchly did not themselves first invent the automatic electronic digital computer, but instead derived that subject matter from one Dr. John Vincent Atanasoff".

Between 1954 and 1973, Atanasoff was a witness in the legal actions brought by various parties to invalidate electronic computing patents issued to Mauchly and [[J. Presper Eckert]], which were owned by computer manufacturer [[Sperry Corporation#Sperry Rand|Sperry Rand]]. In the 1973 decision of ''Honeywell v. Sperry Rand'', a federal judge named Atanasoff the inventor of the electronic digital computer.

==Postwar life==
Following [[World War II]] Atanasoff remained with the government and developed specialized [[seismograph]]s and micro[[barograph]]s for long-range [[explosive detection]]. In 1952 he founded and led the Ordnance Engineering Corporation, selling the company to [[Aerojet General]] Corporation in 1956 and becoming Aerojet's Atlantic Division president.<ref name="NYT"/> He retired from Aerojet in 1961.<ref name="NYT"/>

In 1960 Atanasoff and his wife Alice moved to their hilltop farm in [[New Market, Maryland]] for their retirement.((citation needed|date=June 2021)) In 1961 he started another company, [[Cybernetics]] Incorporated, in [[Frederick, Maryland]] which he operated for 20 years.((citation needed|date=June 2021)) He developed a phonetic alphabet for computers during this period of his life.<ref name="NYT"/> He was gradually drawn into the legal disputes being contested by the fast-growing computer companies [[Honeywell]] and Sperry Rand. Following the resolution of ''Honeywell v. Sperry Rand'', Atanasoff was warmly honored by Iowa State College, which had since become Iowa State University, and more awards followed.((citation needed|date=June 2021))

Atanasoff died at the age of 91 on June 15, 1995, of a [[stroke]] at his home after a lengthy illness.<ref name="NYT">((cite news|url=https://www.nytimes.com/1995/06/17/obituaries/john-v-atanasoff-91-dies-early-computer-researcher.html|title=John V. Atanasoff, 91, Dies; Early Computer Researcher|work=[[The New York Times]]|date=June 17, 1995|author=Walter R. Baranger))</ref> He is buried in Pine Grove Cemetery in [[Mount Airy, Maryland]].((citation needed|date=June 2021))

==Heritage==
Atanasoff visited [[People's Republic of Bulgaria|Bulgaria]] twice, in 1975 and 1985.<ref>((cite web |url=https://m.president.bg/en/cat39/Biography-Jonh-Atanasoff |title=Biography of John Atanasoff |website=president.bg |access-date=2024-02-01))</ref> He visited Boyadzhik village, where his grandfather had been shot by the [[Ottoman Turks]], and was warmly welcomed by the locals and his father's relatives. He was made an honorable citizen of the town of Yambol, and received the "Key of the Town". He was also given various titles by the [[Bulgarian Academy of Sciences]]. The John Atanasov prize is awarded every year in Bulgaria. The [[3546 Atanasoff]] asteroid found at the Bulgarian astronomic observatory of Rozen, was named after him.<ref>((cite web|title=Minor Planet Center, object 3546|url=http://www.minorplanetcenter.net/db_search/show_object?utf8=%E2%9C%93&object_id=3546|publisher=Minor Planet Center|access-date=2 November 2016))</ref>
