Biographical history

Leo Yaffe was born in Devil's Lake, North Dakota. He earned a B.Sc. in chemistry from the University of Manitoba in 1940, an M.Sc. in 1941 and a doctorate in radiochemistry from McGill in 1943. From 1943 until 1952, he worked for Atomic Energy of Canada Ltd. as a project leader in nuclear chemistry and tracer research. Yaffe returned to McGill as a Lecturer in 1954, was promoted to Associate Professor in 1954, and was named Macdonald Professor of Chemistry in 1958. From 1963 to 1968 he directed research at the International Atomic Energy Agency in Vienna. He served as Chairman of the Chemistry Department form 1965 to 1972, and as Vice-Principal (Administration) from 1974 to 1981.

Custodial history

Scope and content

Yaffe's papers reflect his interest in the history of McGill and of chemistry, as well as his involvement in the construction of the Otto Maass Chemistry Building. Historical materials include photographs of F.M.G. Johnson, cartoons of McGill personalities as well as eight original Johnson cartoons; approximately 60 photographs of a chemical laboratory near Trenton, Ontario (ca 1910); snapshots of the Chemistry Department Ph.D. Open House (1967); portraits of McGill chemistry professors; clippings and biographical notices of McGill and chemistry interest; and an autograph document by Otto Maass agreeing to a division of profits from a discovery with W.H. Hatcher. Files on the Otto Maass building largely comprise photographs (approximately 115) of the building under construction and of the opening ceremonies as well as speeches, press notices, and related correspondence.
