John J. Jonas (born 1932) was born in Montreal and graduated from McGill University with a bachelor's degree in Metallurgical Engineering in 1954. He later attended Cambridge University on an Athlone Fellowship and received a Ph.D. degree in Mechanical Sciences in 1960. On returning to Montreal, he began teaching "mechanical metallurgy" at McGill and built up a research laboratory that includes a number of specialized testing machines and is particularly well equipped for experimental investigations in the field of high temperature deformation.
