J. Presper Eckert and John Mauchly, at the University of Pennsylvania, designed and assembled ENIAC (Electronic Numerical Integrator and Calculator).
This huge electronic computer, the first general-purpose computer in the world, was built to solve ballistics problems for the U.S. Army and was hundreds of times faster than any of its mechanical counterparts.
1947 The success of ENIAC prompted Eckert and Mauchly to form their own computer company.
1949 they completed BINAC (Binary Automatic Computer) for the Northrop Corporation in California.
1950 Another computer, which they called UNIVAC (Universal Automatic Computer), had been only partially completed when their company was acquired by Remington Rand.
1951 The first model of the UNIVAC I Series was delivered to the U.S. Bureau of the Census.
