Simon E. Gluck was an engineer educated at the University of Pennsylvania's Moore School of Electrical Engineering, who worked on most of its computer projects during the late 1940s and early 1950s. He was later associated with the Burroughs Corporation, working as an engineer at its Paoli, Pennsylvania, plant.

Between 1943 and 1951, John W. Mauchly and J. Presper Eckert and their associates at the Moore School of Electrical Engineering built six of the world's first electronic digital computers. This work began in 1943 under an Army Ordnance Dept. contract which funded the ENIAC (Electronic numerical integrator and computer). After the Second World War, the staff of the Moore School built the EDVAC and BINAC, computers with stored-memory capability. In 1948 the SPEAC computer was built for the National Bureau of Standards to be used by the Air Controller's Office, and in 1951 the MSAC (Moore School automatic computer) was built for the Army Signal Corps.

Finally, in 1951, Eckert and Mauchly had organized the Eckert-Mauchly Computer Corporation and built the UNIVAC I, the first computer designed for commercial use.
