John Vincent Atanasoff, 1903-10-04 - 1995-06-15. An American mathemetical physicist, and the inventor of the electronic digital computer. Between 1937 and 1942 he built the Atanasoff-Berry Computer with Clifford Berry, at the Iowa State University.

Atanasoff was born on 1903-10-04 in Hamilton, New York. In 1925, he got a Bachelor of Science degree in Electrical Engineering from the University of Florida. In 1926 he received a Master's degree in Maths from Iowa State University. He received a PhD as a theoretical physicist from the University of Wisconsin in 1930.

While an associate professor of mathematics and physics at Iowa State University, Atanasoff began to envision a digital computational device, believing analogue devices to be too restrictive. Whilst working on his electronic digital computer, Atanasoff was introduced to a graduate student named Clifford Berry, who helped him build the computer.

The first prototype of the Atanasoff-Berry Computer was demonstrated in December 1939. Although no patent was awarded for the new computer, in 1973 US District Judge Earl R. Larson declared Atanasoff the inventor of the digital computer (declaring the ENIAC patent invalid).

Atanasoff was awarded the National Medal of Technology by US President Bush on 1990-11-13. He died following a stroke on 1995-06-15.
