In 1943 the U.S. Army contracted the University of Pennsylvania's Moore School of Electrical Engineering to develop a calculator to compute artillery firing tables. Early in 1946, the Computer Age began when Penn engineers J. Presper Eckert and J.W. Mauchly unveiled the Electronic Numerical Integrator and Computer (ENIAC), the world's first general-purpose electronic computer.
