G. F. D. Duff is Associate Professor of Mathematics, University of Toronto. He graduated from the University of Toronto in 1948 and received his M.A. degree in 1949 on the basis of a paper published in the 'Canadian Journal of Mathematics"; this is the only time the M.A. has been given in this way at Toronto. He was elected Proctor Fellow at Princeton 1950-1 and received his Ph.D. degree in 1951. In the following year he was Moore Instructor at Massachusetts Institute of Technology and joined the staff at Toronto in 1952. He is now Editor-in-Chief of the "Canadian Journal of Mathematics".

John Sydney Dugdale, M.A., D.Phil., Principal Research Officer, Division of Pure Physics, National Research Council, Ottawa, is particularly distinguished for his work in high-pressure physics at low temperatures. With Sir Francis Simon, Oxford, he determined the melting parameters for solid helium up to 3000 atmospheres. He has been responsible for establishing a high-pressure laboratory in the National Research Council, contributing to the study of the electrical resistivity of metals, the melting curves of hydrogen and deuterium, and the martensitic transformation in alkali metals. He has considered related theoretical problems, including the thermodynamic properties of linear chains and the role of zero-point energy, in the properties of the inert gas solids.

Moira Dunbar has made studies of the ice of the Canadian Arctic for more than two decades, involving participation in a dozen expeditions.
