Clapp, C. H. (Charles Horace), 1883-1935

Charles H. Clapp was born in Boston, Massachusetts on June 5, 1883. He received his B.A. from Massachusetts Institute of Technology in 1905 and five years later he received his doctorate from the same school before studying at Harvard University. He served as an instructor in geology and mining and assistant state geologist for the University of North Dakota from 1905 to 1907. From 1907 to 1910 he was an instructor of geology and mining at the Massachusetts Institute of Technology. Beginning in 1913 he served as a professor of geology at the University of Arizona until he accepted a similar position at the Montana School of Mines in Butte, Montana in 1916. In 1918 he became president of the Montana School of Mines where he continued teaching as well until 1921 when he was made president of the State University at Missoula (now The University of Montana-Missoula).

Clapp maintained his interest in geology. As late as the 1930s his accomplishments in the field included a study of the granite mass known as the Idaho batholith in the Bitter Root and Sapphire ranges and a geologic survey of several sites proposed for a Chain of Lakes dam project north of Havre, Montana.
