In its day, the Electronic Numerical Integrator and Computer, or ENIAC, was a revolutionary machine. Created under the direction of John Mauchly and J. Presper Eckert of Penn's Moore School of Electrical Engineering (now the School of Engineering and Applied Science), ENIAC was important to the history of Philadelphia, as well as the digital age that it helped to usher in.
Construction of the 27-ton, 680-square-foot computer began in July 1943 and was announced to the public on Feb. 14, 1946. It was built to calculate ballistic trajectories for the Army during World War II, a time- and labor-intensive process that had previously been performed by teams of mathematicians working with mechanical calculators.
