Diamond Jenness 1886-1969
Diamond Jenness was born in New Zealand and educated there and at Oxford. After field work in New Guinea he joined the 1913 Canadian Arctic Expedition, embarking on a career that made him the dean of Canadian anthropologists. Although known for his work on the Copper Eskimos and his identification of the Dorset culture, he did field studies of many other native groups, and his Indians of Canada (1931) was long considered a definitive work. Jenness retired in 1947 after a distinguished career with the National Museum and the Geographical Board, but continued writing for two decades.
