Born in New York in 1834 and raised in the Midwest, John Wesley Powell developed an early love of science and the outdoors. He served in the Union Army during the Civil War and lost his right arm at the Battle of Shiloh, an injury that never stopped him from pursuing demanding fieldwork.
Powell became famous after leading an 1869 river expedition down the Green and Colorado rivers, including a historic journey through the Grand Canyon. The trip helped make him a national figure, and he later led more expeditions in the West while building a career as a geologist, explorer, and teacher.
He went on to direct the U.S. Geological Survey and also led the Smithsonian's Bureau of Ethnology. Powell is remembered not only for his dramatic expeditions, but also for his serious thinking about the American West, especially his warnings about water, land use, and settlement in arid regions.
