David Siminovitch is internationally renowned for his contributions to our knowledge of frost resistance and cold hardening in plants. Beginning with his early demonstration of 'lipoid film' in the plasma membrane and continuing through studies on the changes in carbohydrates, proteins, enzymatic activity and molecular control mechanisms in hardening, his researches have now returned full circle to work on membranes through his recent demonstration that dehydrative freezing damage in liposomal bilayer model systems is analogous to freezing damage in living cells. In addition to his research, Dr. Siminovitch has exerted an important influence on Canadian Plant Science, not only by promoting high standards of research in the Canada Department of Agriculture, but also through his contributions to the Canadian Society of Plant Physiologists and to a series of international symposia on frost resistance from 1940 to 1970.

J.J. Simpson has made several important experimental contributions to nuclear and elementary particle physics, especially to our knowledge of the mass and nature of neutrinos - the most elusive of all particles. SIMPSON has invented a new and very simple method to measure the neutrino mass by tritium implantation in an x-ray detector; this method led him to new limits on the mass of the neutrino. He has obtained new information on the neutrino through the determination of a new limit on the double beta decay lifetime in the largest Germanium detector ever constructed and operated underground in a salt mine.

Ernest Sirluck is a graduate of the University of Manitoba, where he was a student of Professor E. K. Brown. After graduation he was commissioned in the army, and distinguished himself on active service in the European campaign. At the end of the war, he entered the School of Graduate Studies at Toronto, doing research on Milton under A. S. P. Woodhouse, who always spoke of him with affection and admiration as one of his most brilliant students. Dr. Sirluck also taught in University College and his unusual combination of military discipline, barrack-square voice, and imaginative and scholarly teaching made him something of a legendary figure around whom a number of good stories accumulated, most of them authentic. The brilliance of his mind and the firm energy of his character marked him for academic success, and in 1947 the University of Chicago appointed him to the Department of English. His publications on Milton and other seventeenth-century writers soon established his reputation, and he was invited to edit the second volume in the Yale edition of Milton's complete prose works, a volume which appeared in 1959, and whose reception established him as one of the continent's leading Miltonists. In 1962 he was invited to return to Toronto as Professor of English in University College and Associate Dean of the School of Graduate Studies. He succeeded Andrew Gordon as Dean, but retained his position and function in the Department of English, where he continues to offer Milton courses and to give public lectures. His very considerable abilities as an administrator have not quenched his powers or his enthusiasm for scholarship; he reigns without the tragic dichotomy which ruined that other Miltonic archangel.

JOSEF SKVORECKY, Department of English, Erindale College, considered internationally as one of the world's finest living writers, holder of the 1980 Neustadt prize, was a leading figure in the 'new wave' in film and literature which led to the Prague Spring. In his native Czechoslovakia, as novelist, short story writer, film-writer, practitioner of and commentator on jazz, translator and critic of major American novelists, he achieved prominence before coming to Canada in 1968. Within a decade he became recognized as one of Canada's leading writers, critics, and film historians. A stimulating teacher, lecturer, and broadcaster, he has also found time to found, with his wife, the Czech-language publishing firm, Sixty-Eight, which has published over 100 books in Czech and Slovak for a world-wide audience.

John Slykhuis is the leading Canadian on cereal viruses whose discoveries have given him an international reputation. His original discoveries include: the 'spermatosphere' of germinating grass seeds; six new virus deseases of cereals in Canada, England and Europe, and in most instances their insect carriers and practical control measures. He was the first to prove that mites transmit plant viruses. He has been invited to visit many countries to survey their cereal crops for virus diseases, and he is a past president of the Canadian Phytopathological Society.

Professeure à Carleton University, où elle fut directrice de l'Institute of Canadian Studies, Patricia Smart est une éminente spécialiste canadienne-anglaise de la littérature québécoise. Elle est membre actif de quatre comités de rédaction de revues. Ses communications, ses publications sont nombreuses, variées, cohérentes et d'une rare qualité. « Hubert Aquin, agent double » (1973), le premier livre sur cet écrivain, demeure un « classique » et « Écrire dans la maison du père » renouvelle complètement, d'un point de vue féministe éclairé, la lecture du roman québécois traditionnel et contemporain.

Le nom de Wladimir Smirnoff évoque dans les milieux scientifiques la lutte biologique aux insectes nuisibles à l'aide d'entomopathogènes et chez le public averti la lutte à la tordeuse des bourgeons de l'épinette à l'aide du B.T. (Bacillus Thuringiensis) épandu du haut des airs. En effet, ce chercheur et professeur a acquis depuis un grand nombre d'années une réputation internationale par ses travaux sur la biologie des virus et des microorganismes entomophages et particulièrement par ses études fondamentales sur le Bacillus Thuringiensis. Ses recherches l'ont ainsi conduit à étudier les réactions de ces microorganismes aux facteurs du milieu dans le but de trouver un moyen d'augmenter leur virulence. Wladimir Smirnoff a toujours cherché des applications pratiques à ses recherches les plus fondamentales, aussi peut-on le considérer comme l'un des premiers bio-technologistes au Canada.
