John Wesley Powell (1834 - 1902)
John Wesley Powell (March 24, 1834 – September 23, 1902) was a U.S. soldier, geologist, explorer of the American West, professor at Illinois State University, and director of major scientific and cultural institutions. He is famous for the 1869 Powell Geographic Expedition, a three-month river trip down the Green and Colorado rivers that included the first known passage through the Grand Canyon. Powell served as second director of the US Geological Survey (1881–1894) and proposed policies for development of the arid West which were prescient for his accurate evaluation of conditions. He was director of the Bureau of Ethnology at the Smithsonian Institution, where he supported linguistic and sociological research and publications. Lake Powell, a reservoir on the Colorado River, was named in his honor.
