Obituary: Clarence Dan Johnson (1931-2005)

Abstract

In 1966, he joined the faculty of Northern Arizona University at Flagstaff as assistant professor, became an associate professor in 1970 and served as a full professor from 1976 until his retirement in 1994. He was a world authority on the classification of the beetle family Bruchidae, especially in their associations with host plants. Most of his students chose as their thesis subjects some aspect of bruchid taxonomy or their life history, and many of his more than 175 papers were in collaboration with students, or with colleagues. His numerous collecting trips in western United States, Mexico, Central America and northern South America provided study material for him and his students, and his colleagues. He was still publishing papers in 2005. His extensive collection of Bruchidae is now deposited in the arthropod collection of Texas A & M University, College Station.
