Atanasoff Berry Computer

History of the first computer invented. The first computer ever made was Atanasoff Berry Computer (ABC). The Atanasoff-Berry Computer was the world's first electronic digital computer, according to a 1973 court ruling by US Federal Judge Earl R. Larson. It was built by John Vincent Atanasoff and Clifford Berry at Iowa State University during the period of 1937 to 1942. The new device incorporated several major innovations in computing, including the use of binary arithmetic, regenerative memory, parallel processing, and separation of memory and computing functions. The Atanasoff-Berry ruling ultimately superceded and invalidated the ENIAC patent of Mauchly and Eckert and named John Vincent Atanasoff the inventor of the electronic digital computer.
