James V. Wright has tirelessly pursued a programme of archaeological survey, excavation, and synthesis that has contributed outstandingly to an understanding of the cultural development of the boreal forest and eastern woodland areas of Canada in prehistoric times. He has also played a major role in promoting archaeological research in Canada, coordinating the work of amateur and professional archaeologists, increasing public awareness of the need to conserve our country's prehistoric cultural heritage, and communicating to the general public an accurate understanding of Canadian prehistory.

Hugh Wynne-Edwards has had a profound influence on our understanding of Canadian Precambrian rocks. His modification and expansion of the concept of flow folding, his novel hypothesis on the emplacement of granitic rocks, and his challenging new ideas on the tectonic history of the Grenville Province, based on rigorous field and laboratory studies, has stimulated constructive controversy among Canadian Precambrian geologists and has drawn international attention to the problems of our deep zone metamorphic rocks. In addition, despite his youth, he has acquired an enviable reputation as an interdisciplinary research manager and also as an educator and lecturer.
