Josiah Dwight Whitney

Died 19 Aug 1896 at age 76 (born 23 Nov 1819). 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.
