Fred Roots
Ernest Frederick "Fred" Roots  (5 July 1923 – 18 October 2016) was a Canadian geologist, polar explorer, educator and public servant. After graduating with undergraduate and master's degrees in geology from the University of British Columbia and a doctorate from Princeton University, Roots joined the Scott Polar Research Institute and was appointed Chief Geologist for the 1949 to 1952 Norwegian–British–Swedish Antarctic Expedition. During the expedition, in addition to ground-breaking geological and glaciological research studies, he made a 189-day, unsupported dog sled journey across the continent; a record that still stood at the time of his death over six decades later. On his return to Canada he joined the Geological Survey of Canada with whom he served as a field geologist until 1958, when he left to help found the Polar Continental Shelf Program. After 14 years with PCSP, Roots left to act as science advisor to the newly created federal Department of the Environment, where he remained on staff until 1989.
