Strahler, Arthur (1918–2002)

Arthur N. Strahler earned his doctorate in geomorphology at Columbia University, emerging in 1945 as a classically trained Davisian (read qualitative) geomorphologist. However, his personal dissatisfaction with this kind of geomorphology was soon fueled by exposure to the seminal work of Robert Horton. During the 1950s, Strahler was a great pioneer of quantitative geomorphology founded on physical and chemical principles. His influence was greatly extended by the impact of his doctoral students, including Richard Chorley, Donald Coates, Marie Morisawa, and Stanley Schumm.
