Selwyn Hannington Dewdney was born October 22, 1909 in Prince Albert, Saskatchewan. He and his family moved to Kenora, Ontario. Selwyn received his primary and secondary education in Prince Albert and Kenora. He enrolled at the University of Toronto, earning his B. A. in 1931. In 1932 he received a High School Assistant’s Certificate, Science and Mathematics, and an Art Specialist’s Certificate from the Ontario College of Education in 1932. From 1934 to 1936, Dewdney attended the Ontario College of Art, and was named an Associate, OCA, with Honours. He spent several summers travelling thousands of miles, often by canoe, in northern Canada, accompanying his father on visits to northern missions as a student missionary and as a member of a Geological Survey of Canada crew. He moved to London, Ontario in 1936 to take a position as High School Assistant and Art Specialist at Sir Adam Beck Collegiate Institute. He held that position until 1945. Dewdney published his first novel, Wind Without Rain, in 1946. One of the first London artists to paint abstracts in the 1940s and early 1950s, Dewdney painted a number of murals on commission for several clients, including Sir Adam Beck Collegiate and Victorian Hospital. He had virtually stopped painting by the end of the 1950s to devote his time to other interests, but remained active in the local art community. Dewdney served as president of the Western Art League in 1957 and 1960, and from 1960 to 1962 was Executive Director of the short-lived Artists’ Workshop in London. In 1953, Selwyn Dewdney was appointed psychiatric art therapist at Westminster (now Parkwood) Hospital and began using art to help in the treatment of psychiatric patients. He was soon joined in this work by his wife Irene. Selwyn published a number of journal articles and lectured on their art therapy approach. Together, the Dewdney’s pioneered an objective, client-oriented technique that developed into the first art therapy program in Canada. While Irene continued with art therapy work, Selwyn began to devote more of his time to his pioneering studies of Canadian native rock art. Conducting extensive field work for a number of museums, foundations, government departments and the Canada Council, Dewdney recorded 290 rock art sites in Alberta, Saskatchewan, Manitoba, Ontario, Quebec, the Northwest Territories, Michigan and Minnesota, and conducted studies of selected sites. He lecture on native art at various museums, universities and conferences; submitted a number of reports and articles for journals and museum and government department publications. Dewdney co-founded and was elected Senior Associate of Canadian Rock Art Associates. His continuing interest in Canadian native art extended to publishing a number of journal articles, lecturing at the Ontario College of Art, writing Sacred Scrolls of the Southern Ojibway (1975), and serving on the boards of N’Amerind, the Ontario division of the Indian-Eskimo Association, and Indian Crafts of Canada. Dewdney married Irene Maude Donner in 1936. The Dewdneys had four sons: Donner, Keewatin, Peter and Christopher. Selwyn Dewdney died following heart surgery on November 18, 1979.
