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

Computer pioneers 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 between 1943 and 1951. This work began under an Army Ordnance Dept. contract which funded the ENIAC (Electronic Numerical Integrator And Computer) in 1943. After World War Two the staff of the Moore School built the EDVAC and BINAC, computers with stored-memory capability. The MSAC (Moore School automatic computer) was built for the Army Signal Corps in 1951.
