as the Research Building; several years later it was expanded and named the Thomas Hinman Research Building, after Atlanta dentist and university donor Thomas Hinman. After Vaughan left for the Tennessee Valley Authority in 1940, Harold Bunger (head of the Chemistry Department) took over as acting director. However, Bunger died not long thereafter in August 1941. Bunger's successor was Gerald Rosselot, who had been appointed assistant director by Georgia Tech's president in 1940. World War II The number and value of contracts coming to the station significantly increased during World War II; the 1943–1944 budget was the first in which industry and government contracts exceeded the station's other income, most notably, its state appropriation. Director Vaughan had initially prepared the faculty for fewer incoming contracts as the Georgia General Assembly had cut the station's appropriation by 40%, but increased support from industry and government eventually compensated for lower state funding. World War II is credited with GTRI's entry into electronics, especially telecommunications and electronic warfare; the electronics and communications work that Director Rosselot attracted is still a mainstay of GTRI research. Two of the larger projects were a study on the propagation of electromagnetic waves, and United States Navy–sponsored radar research. At the end of World War II, Georgia Tech had about $240,000 (equivalent to $ in ) annually in sponsored research. Important investments during Rosselot's administration at the Engineering Experiment Station included the purchase of an electron microscope in 1946 for $13,000 (equivalent to $ in ), the first such instrument in the Southeastern United States and one of few in the United States at the time. The Research Building was expanded, and a $300,000 (equivalent to $ in ) Westinghouse A-C network calculator was given to Georgia Tech by Georgia Power in 1947. Rosselot's administration included the 1946 establishment of the Industrial Development Council, renamed to the Georgia Tech Research Institute in 1948 and its present name, the Georgia Tech Research Corporation, in 1984. The Georgia Board of Regents had ruled that all money received in a year had to be spent that year, which was problematic because most government contracts the EES had received spanned multiple years. Georgia Tech president Blake Van Leer and vice president Cherry Emerson solution was to create the Industrial Development Council, a non-profit corporation that would manage contracts for research services and subsequently hire the Engineering Experiment Station to perform the research.
