Name:
Named in 1925 by Charles Palache and Helen E. Vassar in honor of US geologist, Raphael Pumpelly [September 8, 1837 Owego, New York, USA – August 10, 1923 Newport, Rhode Island, USA]. The chemical suffix was added in 1973 by the IMA. Pumpelly was an active mining consultant and was professor of Mining Science at Harvard University. He was appointed director of the New England branch of the U. S. Geological Survey in 1884.
