Raymond Thorsteinsson is an Arctic Geologist on the staff of the Geological Survey of Canada. He is a prolific scientist, a specialist in many lines of investigation, an Arctic explorer, and a literate writer and speaker. He is widely consulted as an expert on the stratigraphy and structure of the Arctic Archipelago, an investigator of graptolites of international repute, a student of fusilinids and a most competent observer of geographical aspects of the Arctic. His published works have become standards of reference in Arctic geology and in stratigraphic and systematic palaeontology.

Professor James E. Till has participated in research on physical, biological, clinical, epidemiological and bioethical topics, with a particular emphasis on aspects of those topics that are relevant to cancer control. His initial research was in radiation physics and radiation biology. This evolved into research in cellular biology, with a particular emphasis on stem cells of the blood-forming system, but including some contributions to leukemia research, cellular immunology and somatic cell genetics. Subsequent research was in a different area, with an emphasis on issues relevant to cancer-related decision making, communication and quality of life. Some contributions were also made to research ethics. A long-term interest has been the education and career development of individuals involved in cancer research, cancer care, and cancer control.

The history of condensed matter physics in the last several decades has tracked the discovery of ever more complex solids, some with totally new and unexpected properties. Throughout his career, Prof. Timusk has been in the forefront of these developments. Using infrared techniques with great skill, careful analysis, attention to detail and unique theoretical insight, he has managed to make outstanding contributions to the study of optical properties of point defects in insulators, the electron-phonon coupling, the spectral function in conventional superconductors, electron-hole plasma in semiconductors, quasi-one-dimensional organic metals and superconductors, the metal-insulator transition, the heavy fermions, the high Tc oxides and, most recently, quasicrystals. Not only is he a superb experimentalist with a fine eye for significant problems, but he has also provided many highly imaginative interpretations of his data.

Tobe is a leader in research in insect endocrinology. He has developed and exploited the radiochemical assay for juvenile hormone production to study the pathway of juvenile hormone biosynthesis, the regulation of juvenile hormone biosynthesis and release and the role of this hormone in reproduction and metamorphosis, His work focusses on the feedback loops between the central nervous system the endocrine glands and the reproductive organs which show remarkable similarities with comparable vertebrate systems. Since his first paper in 1967 he has published 100 papers (1986), showing him to be one of the most productive biologists in Canada. This has been recognized by awards such as the Steacie Memorial Fellowship in 1982. His work has and will continue to have a strong impact on biology.

Nicole Tomczak-Jaegermann is a leading researcher in the mathematical theory of Banach spaces who has initiated several novel directions of study and has solved a number of difficult long-standing problems. She is the leading expert on the Banach-Mazur distance between convex bodies. Her work with Komorowski constituted a major component of the recent celebrated resolution of Banach's homogeneous space problem. In collaboration with König she combined techniques from several mathematical disciplines to solve the projective constants problem in a remarkable piece of original research. Her achievements and ideas have had a major impact on both the infinite- and finite-dimensional theory of Banach spaces.

Dr. Towers has achieved an international reputation by virtue of his researches on the physiology and biochemistry of plants. An excellent teacher and an original and talented scientist Dr. Towers is popular with both colleagues and students. In addition to membership in the Canadian Society of Plant Physiologists and the Plant Phenolics Group of North America, he is a Fellow of the Linnean Society. Most of his research has been done during the past nine years while on the staff of the Botany Department at McGill University and heavily engaged in teaching. He is continuing with both research and training of graduate students at the Atlantic Regional Laboratory, where he is head of the Plant Physiology Section with the rank of Senior Research Officer. In addition he has a part-time appointment as an associate professor in the Department of Biology, Dalhousie University. His research has concentrated primarily on the biosynthesis of keto and amino acids and phenolic compounds in a number of different plant species.

La carrière de Marc-Adélard Tremblay se caractérise par un juste équilibre entre l'enseignement, la recherche, la publication et la participation à la vie communautaire, tant québécoise que canadienne. A l'origine de l'enseignement de l'ethnologie à l'Université Laval, il continue d'y exercer une influence déterminante. Ses expériences de recherches se sont poursuivies sur des terrains multiples et ont apporté des éclairages nouveaux sur l'impact de l'avancement technique sur les structures sociales traditionnelles et sur l'adaptation psycho-sociologique des individus. Il faut mentionner spécialement son étude fondamentale sur les besoins, les conditions de vie et les aspirations des familles canadiennes-françaises. Ses recherches ont fait l'objet de publications scientifiques. Il a publié 6 ouvrages et une cinquantaine d'articles. Il a publié une vingtaine d'ouvrages et près de deux cents articles.
