Electronic Numerical Integrator And Computer

ENIAC was the first electronic general-purpose computer. It was Turing-complete, digital, and capable of being reprogrammed to solve a full range of computing problems.

ENIAC was conceived and designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania.  ENIAC was designed to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory.

ENIAC's design and construction was financed by the United States Army during World War II. The construction contract was signed on June 5, 1943, and work on the computer began in secret by the University of Pennsylvania's Moore School of Electrical Engineering starting the following month under the code name "Project PX".

The completed machine was announced to the public the evening of February 14, 1946 and formally dedicated the next day at the University of Pennsylvania, having cost almost $500,000 (approximately $6,000,000 today). It was formally accepted by the U.S. Army Ordnance Corps in July 1946. In 1987ENIAC was named an IEEE Milestone
