Clayton Oscar Person

Clayton Oscar Person, CM FRSC (May 16, 1922 – September 1, 1990) was recognized internationally as an authority on the genetics of host-parasite relations. He was born and raised in Aylesbury, Saskatchewan, Canada and died in Vancouver, British Columbia, Canada. His writings have made a major contribution to the development of a rigorous theoretical basis for our understanding of how the genetic structure of parasitic populations interacts with that of their host populations. This was known as the gene-for-gene relationship. His theoretical methods have been applied widely in the practical management of parasitic diseases in agriculture and forestry.

After service overseas in the Royal Canadian Navy from 1941-1945, he returned to enroll at the University of Saskatchewan where he was awarded Honours in Biology in 1950 and the MA in 1951. He studied for the Ph.D. at the University of Alberta, then spent two post-doctoral years abroad — one at the University of Lund, Sweden and another at the John Innes Institute in England.

Dr. Person was employed for several years (1956-1961) as Research Officer with Agriculture Canada in its Dominion Rust Research Laboratory, Winnipeg. He was then appointed as the first Head of the Department of Genetics at the University of Alberta. In 1966 he joined the Department of Botany of the University of British Columbia. Dr. Person has served the Canadian scientific community in various capacities, including participation in the establishment of the Genetics Society of Canada and later as its president; as Chairman of the NSERC Committee for Plant Biology, and as a member of the Canadian National Committee for the International Union of Biological Science. His scholarly achievements have received wide recognition.
