Donald James Le Roy
Donald James Le Roy, physical chemist, science adviser (b at Detroit, Mich 5 Mar 1913; d at Ottawa 1 Nov 1985). After gaining his PhD at the University of Toronto (1939), he joined E.W.R. STEACIE at the NATIONAL RESEARCH COUNCIL, where he carried out important research on molecular fragments called free radicals, which determine the course of many chemical reactions. In 1944 he joined U of T's chemistry department, becoming chairman in 1960. Through his efforts, the department developed a worldwide reputation in fundamental chemical research. Sharing Steacie's conviction that Canada must increase its scientific stature to survive, LeRoy returned to the NRC in 1969 as vice-president (scientific). In that office (1969-74) and as science adviser at the Science Council (1974-84), he strongly influenced the building of Canada's research capabilities.
