Mauchly worked with John Eckert to build the ENIAC and UNIVAC computers. Mauchly got his doctorate in physics before he took a defense electronics course from Eckert in 1941 at the Moore School of Electrical Engineering. Mauchly had an idea to build a computer that was better than the very limited models available at the time. He and Eckert became good friends.
They went on to work together to build the ENIAC, which was the first general-purpose electronic digital computer. The two formed their own company and developed the first computer produced for sale in the United States, the UNIVAC.
