Robert Donald Hoskin Heard
Robert Donald Hoskin Heard, chemist, biochemist (b at St Thomas, Ont 13 Feb 1908; d at Montréal 8 Sept 1957). Well known for research on the biochemistry of steroid hormones, Heard was largely responsible for the 1944 choice of a Canadian site for the annual prestigious Laurentian Hormone Conference. He was a BA and MA (1930) of the University of Toronto and as an 1851 Exhibition Scholar received his PhD from the University of Manchester (1932). After a year at Oxford, he returned to U of T as a Banting Research Foundation grantee. His university appointments in biochemistry, at Dalhousie in 1937 and McGill in 1942, enabled him to continue his outstanding teaching and research career until his early death. Author of many scientific papers with his students and collaborators, Heard was noted for developing methods for labelling steroid hormones with radioactivity and for using these "tracers" to reveal the pathways of formation and interconversion of ovarian and adrenal hormones.
