Powell, John Wesley (1834–1902), geologist, anthropologist, director of the U.S. Geological Survey (USGS).Born in New York and raised on the Ohio and Illinois frontiers, Powell attended Oberlin College and was a teacher before joining the Union Army in the
Civil War. Losing an arm at the Battle of Shiloh in 1862, he left the military with the rank of major. Active in the Illinois State Natural History Society before the war, he returned in 1865 to become professor of geology at Illinois Wesleyan College. An 1869 expedition down the Colorado River brought Powell national notice and a federal appropriation. His U.S. Geographical and Geological Survey of the
Rocky Mountain region (1870–1879) won him recognition for explaining the role of structure, uplift, and stream erosion in shaping topography. Also a student of native Indian language and culture, Powell organized the
Smithsonian Institution's Bureau of Ethnology in 1879 and directed it until his death.
Concerned about the risks of American expansion into the arid
West, Powell in his 1878
Report on the Lands of the Arid Region of the United States warned policy‐makers about settlement laws that ignored scarcity of water. His desire for a scientific bureau to replace Land Office surveys was partially realized in 1879, when he worked with Clarence King to establish the USGS. Powell became its second director in 1881. Buoyed by a Spencerian faith in science and progress, Powell worked to extend the survey beyond the mining regions and into general geology, topographic mapping, and natural‐resource assessment.
The USGS under Powell won international acclaim. The most prominent federal scientific institution of the late nineteenth century, it laid a foundation for the growth of federal scientific agencies during the
Progressive Era. It also sparked controversy when it clashed with traditional congressional prerogatives. Powell's planning of irrigation development (1888–1890) angered some members of Congress and led to his retirement in 1894.
