Samuel H. “Doc” Knight taught geology at the University of Wyoming in Laramie, Wyo. from 1916 until his retirement in 1963. For a decade he was the only geology teacher, but as his classes began to grow in size and popularity the geology department expanded into a nationally recognized program. He established the university’s science camp in the mountains west of Laramie and revitalized the university’s geological museum. Knight taught an estimated 10,000 students throughout his career and was known to many “Mr. Geology of Wyoming.”
