John AtanasoffDied 15 Jun 1995 at age 91 (born 4 Oct 1903).John Vincent Atanasoff was an American physicist who was belatedly credited (1973) with developing the first electronic digital computer. Built in 1937-42 at Iowa State University by Atanasoff and a graduate student, Clifford Berry, it introduced the ideas of binary arithmetic, regenerative memory, and logic circuits. These ideas were communicated from Atanasoff to John Mauchly, who used them in the design of the better-known ENIAC built and patented several years later. On 19 Oct 1973, a US Federal Judge signed his decision following a lengthy court trial which declared the ENIAC patent invalid and named Atanasoff the original inventor of the electronic digital computer, the Atanasoff- Berry Computer or the ABC. |
