When was the first computer made?
The first programmable electronic digital computer was called the ENIAC (Electronic Numerical Integrator And Computer). The contract to make it was signed on June 5, 1943, and the only one manufactured was on February 14, 1946. It was designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania. For the very earliest computer, see the related link to the Antikythera Mechanism.
- in 1942, the first electronic digital computer, the ABC was built by John V. Atanasoff and his graduate student Clifford Berry. it was built in Ames, Iowa.
- in 1943, the first programmable electronic digital computer, the Colossus was built by Tommy Flowers for Bletchley Park. up to VE day 11 of these computers were built.
- in 1946, ENIAC was finished, as told above.
The first electronic computer was made at Iowa State University, but, alas, it could not be reprogrammed. The "Z" computer was made in Germany, and was the first to be reprogrammable. The British Colossus computer was made at Bletchley Park, UK, but the first general-purpose reprogrammable computer, called ENIAC, was made at the University of Pennsylvania in 1946.
