Remington Rand built the first commercially successful electronic digital computer, UNIVAC I, delivered in 1951.
UNIVAC I was designed by J. Presper Eckert and John Mauchly, who had previously worked on ENIAC. The computer used vacuum tubes and magnetic tape, and it was designed for business and government data processing rather than only scientific calculations.
The first UNIVAC was delivered to the United States Census Bureau in 1951. Its ability to process large volumes of data made it especially notable during the 1952 U.S. presidential election, when a UNIVAC forecast correctly predicted Dwight Eisenhower’s victory.
Remington Rand later merged with Sperry Corporation in 1955, and the resulting company became part of the corporate lineage that eventually led to Unisys. UNIVAC is distinct from ENIAC, which was an earlier electronic general-purpose computer but was not the same commercial system.
