Dr. MacGregor taught at the University of Alberta from 1960 to 1993. During this period he has gained an international reputation for his research into structural engineering and he has been prominent in professional and university affairs. Dr. MacGregor has published extensively, particularly with respect to the behaviour of concrete structures and his research has had substantial impact on professional practice throughout the world, particularly in the design of reinforced concrete columns and the design of prestressed concrete for shear. Recent research has led to a better understanding of the behaviour of concrete containments for nuclear power plants. The engineering profession in both Canada and abroad has relied extensively on Dr. MacGregor's skills in transforming research results into design codes in order to bridge the gap between research and practice.

John Ross Mackay is an outstanding Canadian geographer who has done extensive work in the Arctic. The four main fields of geography which have engaged his interest are the Canadian Arctic, cartographic methods, physiography, and southeast Asia. During the war he was stationed at Darwin, Australia, where he was Senior Intelligence Officer. Dr. Mackay's ability in his chosen field is indicated by the fact that he is Past President of the Canadian Assocaition of Geographers and Past Vice-President of Pacific Coast Geographers, and is a Fellow of these and several other societies. He is currently Professor and Acting Chairman of the Division of Geography at the University of British Columbia. In the past 40 years following my election, I have devoted all of my time to permafrost and no longer work in cartographs and southeast Asia.

Auteur bilingue d'ouvrages et d'articles consacrés à divers aspects de la linguistique, William Mackey occupe au Canada, dans sa spécialité, une situation de premier plan, non seulement par la qualité de son enseignement, la valeur et l'originalité internationalement reconnues de ses écrits, mais aussi par la fonction de consultant qu'il exerce depuis longtemps auprès des instances fédérales et provinciales sur les problèmes linguistiques du Canada. Son rayonnement scientifique à l'étranger est attesté par son active participation aux congrès internationaux. M. Mackey écrit le français aussi bien que l'anglais avec une précision et une élégance que nombre d'unilingues pourraient lui envier.
