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. The collection consists of research reports, progress reports, engineering drawings, published articles, and lecture notes which describe the development of the ENIAC, EDVAC, MSAC, and SEAC computers.

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 collection consists of undated black and white photographs and slides; twelve of the eighteen slides are duplicates of the photographs. Two of the images are engineering drawings (EDVAC's block diagram and control panel) and the rest are images of the EDVAC and MSAC computers.
