Josiah Dwight Whitney

Born 23 Nov 1819; died 19 Aug 1896 at age 76. American geologist and chemist, known for his studies of the regional geology of California. Whitney was an independent consulting expert in mining (1849-54) when he was appointed chemist for the state of Iowa and professor of mineralogy at the University of Iowa. He was California State Geologist (1860-1874). His name was given by a California Geological Survey field party to Mount Whitney (1864) in east-central California, the highest summit on the U.S. mainland outside Alaska. The survey was significant for the men it trained and the methods it introduced - notably topographical mapping by triangulation. During his years in California, Whitney was active in promoting the California Academy of Science, and served as a commissioner of Yosemite Park.
