- atanasoff-berry computer — (computer) (ABC) An early design for a binary calculator, one of the predecessors of the digital computer. The ABC was partially constructed between 1937 and 1942 by Dr. John Vincent Atanasoff and Clifford Berry at Iowa State College. As well as binary arithmetic, it incorporated regenerative memory, parallel processing, and separation of memory and computing functions. The electronic parts were mounted on a rotating drum, making it hybrid electronic/electromechanical. It was designed to handle only a single type of mathematical problem and was not automated. The results of a single calculation cycle had to be retrieved by a human operator, and fed back into the machine with all new instructions, to perform complex operations. It lacked any serious form of logical control or conditional statements. Atanasoff's patent application was denied because he never have a completed, working product. Ideas from the ABC were used in the design of ENIAC (1943-1946).

- john vincent atanasoff — (person) 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.
