(Suggest an Edit or Addition)

According to Wikipedia, Knut Schmidt-Nielsen was a prominent figure in the field of comparative physiology and Professor of Physiology Emeritus at Duke University. Background Born in Trondheim, Norway. He was educated in Oslo and Copenhagen. He became a student in the laboratory of August Krogh in Copenhagen in 1937. Schmidt-Nielsen moved to the United States, where he studied at Swarthmore College, Stanford University, and the University of Cincinnati College of Medicine. He was the leader of expeditions to the Sahara Desert in 1953–54 and central Australia in 1962. He has been a Guggenheim Fellow, a Trustee of Mt. Desert Island Biological Laboratory, and a consultant to the National Science Foundation.
