Earning an Sc.D. in electrical engineering at MIT in 1931, Edgerton spent the rest of his life at the Institute as teacher, researcher, and head of the Stroboscopic Light Lab. His papers, which include documentation of his development of high-speed photography techniques and equipment for underwater exploration, are available for research in the Institute Archives, Building 14N-118.
