John Glen (1927-), physicist and glaciologist, is one of a group of physicists who turned their attention to the mechanisms by which glaciers move during the 1950s. He is best known for obtaining a ‘flow law’ for glacier ice, using a compression machine in a fridge in the Cavendish Laboratory, University of Cambridge. After studying at the University of Cambridge,Glen spent most of his career in the Department of Physics at the University of Birmingham. Throughout his career he was an active member of the International Glaciology Society and in retirement continues as a member of the Editorial Board of the Journal of Glaciology .
