Dr. C. C. Gotlieb is a recognized leader in the field of computer science. He has been largely responsible for the development of the foremost computing centre in Canada, which in turn has sparked the development of computing across the country. He has initiated research in many areas of computing and has led the way in extending the computational approach to various branches of science, engineering and even the humanities. As author, lecturer, editor, and organizer of computing conferences both in Canada and internationally, he has assisted in establishing computation as an important interdisciplinary science. He is at present Editor-in-Chief of one of the two most important computing journals in America.

Professor A.F. Graham is a leading scientist in the field of virus biochemistry. In 1949, he was the first to show the incorporation of a radio-isotope (32p) into a purified mammalian virus. His studies of the break-down phenomenon of phages had very important impact on the concepts of the mutual exclusion effect. Through Dr. Graham and his group's efforts, as well in Philadelphia as in Montreal, human reoviruses are among the best known mammalian viruses, genetically and biochemically. Throughout his career, Dr. Graham was actively involved in teaching at Universities of Edinburgh, Pennsylvania, Toronto and McGill. Presently, he is Professor and Chairman of Biochemistry at McGill University.

Edmond Granirer is an outstanding abstract analyst. He is perhaps best known for his penetrating studies on invariant means on semi-groups, a field in which he is the present day leader. In addition, he has made significant contributions to many other areas of analysis including convexity and the structure theory of convolution and Fourier algebras.

Prof. G.A. Gratzer is recognized as one of the top six workers in the field of Universal algebra and lattice theory. Amongst his ninety research papers there are a number which have solved outstanding problems. Besides his research work, he is a recognized expositor, having published three books which have been well received everywhere. Since coming to Canada, he has integrated himself with the Canadian mathematical community - a fact which is attested to by invitations to give invited lectures at ten Canadian universities. He was awarded the Stacey Prize in 1972.

MICHAEL W. GRAY is the world leader in several areas of molecular and evolutionary biology. He provided the best and earliest proof that mitochondria, respiratory organelles of higher cells, are highly degenerate bacteria. He has discovered a world of molecular diversity in the chromosomes of mitochondria, demonstrating that genes can be thoroughly scrambled and still function, and that in some cases the genetic message must be edited to make sense. He has also made seminal contributions to our understanding of the structure and function of informational RNAs, and enriched our understanding of the evolution of complexity at the molecular level.

Peter Greiner has achieved international recognition for his outstanding work in the theory of partial differential equations. Already his outstanding paper on the asymptotic expansion for the heat equation won him a reputation for fine work in a demanding field. His most recent work, in personal collaboration with leaders of the Princeton school, has resulted in the discovery of conditions for the solvability of the Lewy equation, a challenge to mathematicians for the last twenty years, and in a monograph recording major advances in the 2-Neumann problem which is the threshold of the next generation's work on boundary value problems.

David Griller is distinguished for his outstanding researches on reactive chemical intermediates. He has determined structures, modes of reaction and thermodynamic properties of many short-lived chemical species. He has pioneered in the development of concepts and methodologies that have been avidly adopted by other chemical research workers. Griller's work has laid the foundation for the development of several new synthetic methods and he has tamed highly reactive species using molecular shielding to protect their active sites. His research on reactive intermediates has been both diverse and profound and continues to have a major impact in all areas of chemistry.

Yvan Guindon is one of Canada's most dynamic and brilliant organic chemists under the age of 40. In less than 10 years since his Ph.D. degree, he has gained worldwide recognition for his outstanding contributions to bio-organic, medicinal and organic chemistry. His meteoric rise through the ranks in a highly competitive industrial environment is a reflection of his many talents as a premier scientist and a true leader. In addition to his numerous activities, Dr. Guindon is also an adjunct professor in the department of chemistry at the Université de Montréal. Dr. Guindon is a most deserving candidate to be nominated for fellowship in the Royal Society of Canada.

Ms. Gupta is an internationally acclaimed group theorist who works in many difficult areas of Combinatorial Group Theory. Her most startling discovery of 2-torsion in the free centre by metabelian groups has generated intense research throughout the world. Amongst her many other accomplishments is her work on the automorphism groups and especially on the existence of wild automorphisms in important cases. In the past number of years she has been an important contributor to virtually every international conference on group theory.

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.
