In 1946, the researchers resigned from the University of Pennsylvania and formed the Eckert–Mauchly Computer Corporation.ĮNIAC was a large, modular computer, composed of individual panels to perform different functions. Significant development work was undertaken by the female mathematicians who handled the bulk of the ENIAC programming: Jean Jennings, Marlyn Wescoff, Ruth Lichterman, Betty Snyder, Frances Bilas, and Kay McNulty. Shaw (function tables), Jeffrey Chuan Chu (divider/square-rooter), Thomas Kite Sharpless (master programmer), Frank Mural (master programmer), Arthur Burks (multiplier), Harry Huskey (reader/printer) and Jack Davis (accumulators). The team of design engineers assisting the development included Robert F. Presper Eckert of the University of Pennsylvania, U.S. ĮNIAC was designed by Ursinus College physics professor John Mauchly and J. Goldstine persuaded the Army to fund the project, which put him in charge to oversee it for them.

The construction contract was signed on Jwork on the computer began in secret at the University of Pennsylvania's Moore School of Electrical Engineering the following month, under the code name "Project PX", with John Grist Brainerd as principal investigator. 4 Comparison with other early computersĮNIAC's design and construction was financed by the United States Army, Ordnance Corps, Research and Development Command, led by Major General Gladeon M.3.1 Role in the development of the EDVAC.2.3 Role in development of the Monte Carlo methods.It was transferred to Aberdeen Proving Ground, Maryland in 1947, where it was in continuous operation until 1955. As ENIAC calculated a trajectory in 30 seconds that took a human 20 hours, one ENIAC could replace 2,400 humans. The combination of speed and programmability allowed for thousands more calculations for problems. It had a speed on the order of one thousand times faster than that of electro-mechanical machines this computational power, coupled with general-purpose programmability, excited scientists and industrialists alike. ĮNIAC was formally dedicated at the University of Pennsylvania on February 15, 1946, having cost $487,000 (equivalent to $5,900,000 in 2020), and was heralded as a "Giant Brain" by the press. ĮNIAC was completed in 1945 and first put to work for practical purposes on December 10, 1945. Īlthough ENIAC was designed and primarily used to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory (which later became a part of the Army Research Laboratory), its first program was a study of the feasibility of the thermonuclear weapon. It was Turing-complete and able to solve "a large class of numerical problems" through reprogramming. There were other computers that had these features, but the ENIAC had all of them in one package. 1947–1955)ĮNIAC ( / ˈ ɛ n i æ k/ Electronic Numerical Integrator and Computer) was the first programmable, electronic, general-purpose digital computer, completed in 1945.
