Alastair Graham Walter Cameron, Senior Research Officer, Physics Division, Atomic Energy of Canada Limited, Chalk River, is a world leader in the field of nuclear reactions at high temperatures and densities. A graduate of the University of Manitoba, with a doctor's degree from the University of Saskatchewan in 1952, he has recently been Senior Research Fellow at the California Institute of Technology. His work has led to a better understanding of the nuclear energy processes in stars, of the abundances of different elements in stars, and of the occurrence of stellar nova explosions at high densities and temperatures. Dr. Cameron's sound knowledge of nuclear physics, his bold imagination, and incisive mind have led him to make a remarkable contribution to nuclear astrophysics.

Jack James Ramsey Campbell, Professor of Dairying, Faculty of Agriculture, University of British Columbia, has made an outstanding contribution to research in the field of intermediate microbial metabolism. He has published widely and as a result of the work he has done, he has on two occasions been invited to serve as Visiting Professor at the Graduate Schools of Johns Hopkins University and of the University of Illinois. He has achieved an enviable reputation as a teacher, both at the undergraduate and at the graduate level. He is at present one of the Associate Editors of the "Canadian Journal of Microbiology" and has served for the American Society of Bacteriologists as Associate Editor of "Bacteriological Reviews". He was President of the Physiology Section, American Society of Bacteriologists during the period 1955-56. 1965-82 Head, Dept. of Microbiology, U.B.C. Retired 1983.

In addition to notable theoretical contributions relating to genetic improvement of crop plants, Dr. Campbell has been engaged (since 1949) in producing new varieties of hard spring wheat suited to the Canadian Prairies. These varieties (Pembina, Canthatch, Manitou, Neepawa, Napayo, Benito, Columbus, Katepwa, Roblin) have enabled farmers to consistently produce good crops of high quality grain. During the 1980's circa 17,000,000 acres of land were sown to Dr. Campbell's varieties; these varieties accounted for more than 80% of the total acreage sown to wheat on the prairies, and for more than 95% of the total sown in those areas where the problem of disease (wheat rust) is most serious.

Dr. Campbell's first major contribution to knowledge was a new study of the respiratory muscles in man. Using primitive equipment, but a high degree of ingenuity, he made basic contributions to understanding the control of breathing in man and the way in which the symptom of shortness of breath was signalled in the human body. He broadened his field of study to include the control of arterial blood tensions in man and this work led directly to a re-examination of the methods of treating respiratory failure in the human, which placed this important clinical problem in a new scientific context and introduced a very important modification of traditional treatment which has since been everywhere adopted. He had in addition consistently applied basic scientific knowledge to the investigation of clinical problems, and has made distinguished contributions to the educational field by examining the ways in which the scientific principles underlying medical treatment can be better taught to medical students whose ambitions for themselves are all too often limited by a narrow pragmatic perspective. He has published three major books under his own authorship and collaborated in the production of a further five. His many scientific papers on a variety of topics indicate the breadth of his scientific knowledge and the exordinary ingenuity of his experimental approach to clinical problems. Of his generation, Dr. Moran Campbell is unquestionably one of the most distinguished examples of the success of the rigorous application of scientific method to clinical problems and his career in this field has been one of the most distinguished of any of his contemporaries.
