Powell, John Wesley
Born Mar. 24, 1834, in Mount Morris, N.Y.; died Sept. 23, 1902, in Haven, Me. American geologist and geomorphologist.
Educated at Illinois, Wheaton, and Oberlin colleges, Powell was a professor of geology at Illinois Wesleyan College in Bloomington from 1865 to 1868. He was one of the organizers of the US Geological Survey and served as its director from 1881 to 1894.
The first man to explore the Grand Canyon, Powell established the close relationship between the geological structure of the territory and the forms of relief. His major works played an important part in shaping the theoretical views of the American school of geomorphology, particularly those of W. Davis. Powell held that large stratigraphic units should be distinguished according to lithologic features rather than according to paleontological data.
Powell also studied the way of life of American Indians and proposed a classification of their languages.
