Short for Electronic Numerical Integrator And Calculator, the ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was not completed until 1946. It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons. While not completed until the end of the World War II, the ENIAC was created to help with the war efforts against German forces. To the right is a public-domain U.S. Army Photo of the EDVAC, from K. Kempf. and the History of Computing.

The ENIAC is now being displayed at the Smithsonian Institution in Washington D.C.
