Paul Dahm

Paul A. Dahm was a faculty member of Entomology at Iowa State University for 34 years (1953 to 1987) in Insecticide Toxicology. He was conferred the Charles F. Curtiss Distinguished Professor of Agriculture in 1969, and served as Chairman of the Department of Entomology from 1975 to 1982. Dahm taught courses in Insecticide Toxiciology, Insect Physiology, and Medical and Veterinary Entomology. He served as major professor for 22 Ph.D. and 17 M.S. students and published widely in the areas of insecticide metabolism and environmental fate. He was conferred honorary member of the Entomological Society of America in 1985.

The Paul A. Dahm Memorial Lecture in Entomology is held annually, usually in April. Invited speakers address a range of subjects relating to Insect Toxicology.
