Peter Albertus Hacquebard. The glorious colours of Ottawa's springtime tulips and a man interested in internals of coal seams appear to have little in common. Yet among the postwar transplants from the Netherlands in that city, one of the most successful has been Peter Albertus Hacquebard, born in Rotterdam and educated at the University of Leiden. After a brief flirtation with the oil industry, he joined the Geological Survey of Canada in 1948 and was put in charge of the newly formed Coal Research laboratory at Sydney, Nova Scotia. Since then he has poured out a steady stream of contributions of high scientific merit. His researches in palynology led to the first recognition of coal of Carboniferous age in western Canada. He has made outstanding contributions to the revision of the nomenclature and classification of coal and in the field of coal petrography. His work on age determination and correlation of coal seams by petrographic and spore analysis, the mechanism and causes of spontaneous combustion in coal, and his contribution to the understanding of stress relief 'bumps' in coal mines have earned him an international reputation. He is past Head of Coal Research Section at B.I.O. in Dartmouth, NS and retired in 1983. Presently holds the position of Emeritus Research Scientist.

Ian Halliday, in his original research over nearly thirty years, has shown initiative and brilliance, combined with the qualities of versatility and leadership. He was the first to identify the auroral green line in the spectra of meteors and his definitive lists of lines in meteor-shower spectra are used internationally. He has conducted significant field work at Canadian meteor craters, and his camera network on the Canadian prairies resulted in the recovery of the INNISFREE meteorite. This is the third meteorite in the world collection with an instrumentally determined orbit, and the main mass was actually located by Halliday personally. Data from the camera network (published in 1989) have been used internationally as establishing the present rate of arrival of meteorites on the Earth.

Louis-Edmond Hamelin possède une maîtrise en économique et un doctorat en géographie qui le destinaient naturellement à occuper le poste de professeur titulaire de géographie et directeur de cet institut à Laval, et à être le Directeur-fondateur du Centre d'études nordiques de ladite université. Sa compétence en a fait une sorte d'ambassadeur de son université auprès des institutions spécialisées dans son secteur dans les autres pays. C'est ainsi qu'en 1949 il est à Lisbonne et en Allemagne; en 1952, à Washington; en Argentine en 1957 et I'année suivante en Espagne; puis en Pologne et dans les pays nordiques en 1960. Ces fonctions de représentation ne I'ont pas empêcher de publier - bien au contraire -; 104 communications et conférences ont été présentées dans des congrès au Canada et à I'étranger. Ses champs de recherches sont très variés : le Bas-auphiné en France, Sainte-Marie-de-Bauce au Canada, les IIes de la Madeleine, I'histoire générale de la géographie du Québec, un volume édité en I'honneur du grand géographe français, Raoul Blanchard. Tout cet ensemble représente un travail immense dans une vie professionnelle relativement courte et promet encore davantage pour I'avenir.

B.A. (Manitoba, 1945), M.A. (Toronto, 1949), Ph.D. (Cambridge, 1953). Has taught at Toronto, Cambridge, Washington (for sixteen years), and since 1968 has been Professor of English at Queen's University. He is author or editor of six books and some twenty-four articles and chapters in books. He is internationally recognized as a leading scholar in the field of Renaissance studies, and his work on the poetry of Spenser, and on Sir Philip Sidney and Shakespeare has been widely influential. He has been invited to lecture at many universities in Canada, the United States and Britain, and has held visiting fellowships at Cambridge, at Duke, and at the Huntington Library in California.
