Louis Barker Jaques was born in Toronto on 10 July 1911. He attended the University of Toronto and earned three degrees there: a BA in physiology and biochemistry (1933); MA (1935) and PhD (under the supervision of Dr. C.H. Best, 1941). In 1974 Jaques also earned a DSc from the University of Saskatchewan. From 1934-1944 Dr. Jaques held academic positions at the University of Toronto as a Fellow, research assistant, and lecturer. In 1946 he moved to the University of Saskatchewan with an appointment as professor and head of Physiology. He resigned the headship in 1971, accepting a position as (the first) W.S. Lindsay Professor in the College of Medicine. A scientist of international reputation, Jaques was among the first to demonstrate the usefulness of heparin in treating thrombosis; to demonstrate the effectiveness of dicumarol in thrombosis; and he originated the use of silicone in handling blood. Upon his retirement in 1979 he was named Professor Emeritus; and in 1981 he was named a lay canon by the Anglican diocese of Saskatoon.
