John Vincent Atanasoff OCM (October 4, 1903 – June 15, 1995) was an American physicist and inventor credited with inventing the first electronic digital computer. [1] Atanasoff invented the first electronic digital computer in the 1930s at Iowa State College (now known as Iowa State University).
Conceived in 1937, the machine was built by Iowa State College mathematics and physics professor John Vincent Atanasoff with the help of graduate student Clifford Berry.It was designed only to solve systems of linear equations and was successfully tested in 1942.
In December 1939 John Atanasoff and Clifford Berry completed their experimental model to prove the concept of the Atanasoff–Berry computer (ABC) which began development in 1937. [40] This experimental model is binary, executed addition and subtraction in octal binary code and is the first binary digital electronic computing device.
The Man Who Invented the Computer is a 2010 historical biography by author Jane Smiley about American physicist John Vincent Atanasoff and the invention of the computer. The book follows Atanasoff as he collaborates with others to develop the 1942 Atanasoff–Berry Computer (ABC), the first electronic digital computing device.
Atanasoff, John: Built the first electronic digital computer, the Atanasoff–Berry Computer, though it was neither programmable nor Turing-complete. 1822, 1837 Babbage, Charles: Originated the concept of a programmable general-purpose computer; designed the Analytical Engine and built a prototype for a less powerful mechanical calculator. 1973
For a variety of reasons – including Mauchly's June 1941 examination of the Atanasoff–Berry computer (ABC), prototyped in 1939 by John Atanasoff and Clifford Berry – U.S. patent 3,120,606 for ENIAC, applied for in 1947 and granted in 1964, was voided by the 1973 [97] decision of the landmark federal court case Honeywell, Inc. v. Sperry ...
John Vincent Atanasoff and Clifford Berry create the first electronic non-programmable, digital computing device, the Atanasoff–Berry Computer, that lasted from 1937 to 1942. 1940s [ edit ]
The Atanasoff–Berry computer, a prototype of which was first demonstrated in 1939, is now credited as the first vacuum-tube computer. [1] However, it was not a general-purpose computer, being able to only solve a system of linear equations, and was also not very reliable. The Colossus computer at Bletchley Park
