Dr. J.A. McCarter has consistently and steadily pursued a course of high scholarship and imaginative research. His work has explored the fundamental properites of cellular metabolism and has required the use of tracer techniques, the development of new methods, and biochemical synthetic processes of a high order. He has an international as well as a national reputation in his field, and his work is both imaginative and sound. He has also proved a very able and stimulating teacher who insists on a high scholarship of fundamental learning by his students. His scholarly interests extend beyond biochemistry and his advice and aid is sought in many fields.

Dr. McCulloch has attracted international scientific recognition primarily for his work on the detection and quantitation of stem cells of the blood-forming system. He played a major role in the development of the spleen colony technique for measuring the capacity of primitive normal and neoplastic cells to multiply and differentiate. With his colleagues, he has used this technique to explore many of the fundamental properties of stem cells, and the role of various factors involved in the regulation of stem cell functions. The methods pioneered by Dr. McCulloch and his co-workers are now being used very widely to obtain important information about the normal formation of blood cells, the source and development of immunologically competent cells, the patterns of growth of cancer cells in mice, and the mode of action of chemotherapeutic agents used in the treatment of leukemia. Dr. McCulloch's work has been characterized by a successful combination of a talent for basic research and a deep interest in its practical applications.

Tom McFeat is a Canadian ethnologist of originality and distinction. His interest in traditional ethnology has been linked to sociology and social psychology in the tradition of the Harvard Laboratory of Social Relations. As Chief Ethnologist of the National Museum of Canada from 1959 to 1963, and in university positions, he has stimulated the understanding of the Indian cultures of North America, by his writing and his firm encouragement of the work of others. His work linking ethnography to the theory and method of other disciplines has culminated in his recent book on "Small Group Cultures". This demonstrates that the remote and controlled experiments of the small group laboratory can be applied with insight to the analysis of real situations from those of the army in sophisticated action to the complexities of tribal culture. Tom McFeat's work, widely respected, is daring, provocative, and yet carefully disciplined.

Patrick and Edith McGeer's neurological research is recognized worldwide as responsible for many signal advances in the understanding of Alzheimer's disease and Parkinson's disease, and for the important kainic acid model of Huntington's disease. Their groundbreaking hypotheses on neuroinflammation in neurodegenerative diseases and anti-inflammatory therapy are now strongly supported and part of the main focus for research into Alzheimer's disease.
