Paul H. DeBach (1914-1993) was an internationally recognized proponent of biological insect control. His research on citrus pests was fundamental in preserving the continued health of California citrus crops without reliance on chemical pesticides. DeBach was born in 1914 in Miles City, Montana and moved to southern California at an early age. In 1933, he graduated from Fairfax High School in Hollywood, California and thereafter began his university studies at the University of California, Los Angeles. After two years, he transferred to the University of California, Berkeley, where in 1938, he received his B.A. in entomology. During his graduate studies, DeBach worked with Harry Smith at the University of California, Riverside's Citrus Experiment Station. In 1940, DeBach was awarded a Ph.D. in biological control of insect pests.
