Clifford Berry was born April 19, 1918, in Gladbrook, Iowa, to Fred and Grace Berry. [1] His father owned an appliance repair shop, where he was able to learn about radios. [ 1 ] He graduated from Marengo High School in Marengo , Iowa, in 1934 as the class valedictorian at age 16. [ 2 ]
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).
The Atanasoff–Berry computer (ABC) was the first automatic electronic digital computer. [1] The device was limited by the technology of the day. The ABC's priority is debated among historians of computer technology, because it was neither programmable , nor Turing-complete . [ 2 ]
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 ]
John Vincent Atanasoff (1903–1995), ISU Math M.S. 1926 (see also Atanasoff–Berry Computer), inventor of the first electronic digital computer [22] Clifford E. Berry (1918–1963), B.S. 1939, MS 1941, Ph.D. 1948 (see also Atanasoff–Berry Computer ), co-developer of the first electronic digital computer [ 86 ]
It was constructed in 1939. At Iowa State, he was an early user of John Vincent Atanasoff's Atanasoff–Berry computer (perhaps the first user of an electronic digital computer for real world production mathematics problem solutions). [5]
Durham was a student under John Vincent Atanasoff, who along with his graduate assistant Clifford Berry, invented the world's first electronic digital computer. [2]
The decision held, in part, the following: 1. that the ENIAC inventors had derived the subject matter of the electronic digital computer from the Atanasoff–Berry computer (ABC), prototyped in 1939 by John Atanasoff and Clifford Berry, 2. that Atanasoff should have legal recognition as the inventor of the first electronic digital computer and 3.
