Leslie Callahan, for whom the memorial endowment is named, enjoyed a long and distinguished military career, serving in both the Philippines and Korea. Before his retirement from the US Army as a Colonel with 25 years of service, he had completed overseas and academic tours and held command and staff assignments related to technological development of air defense, guided missiles, avionics, and telecommunication systems.

A 1944 graduate of the US Military Academy, he earned his master’s degree (1951) and Ph.D. (1961) in electrical engineering from the University of Pennsylvania.

He joined the GT faculty in 1969 and taught many undergraduate and graduate Industrial and Systems Engineering (ISYE) courses for the next 16 years. He also played a major role in developing graduate Military Operations Research programs for DoD personnel. He established the Callahan Endowment in 1993.
