Earl Stegman, chairman and professor of agricultural and biosystems engineering at North Dakota State University, retired Saturday after 37 years at NDSU.
A native of Neche, N.D., Stegman received his bachelor's and master's degrees from NDSU and his doctorate from Michigan State University.
He started at NDSU in 1966 as an assistant professor and was promoted to professor in 1974. In 1991, he was appointed chairman of the agricultural engineering department, which he led through the change to agricultural and biosystems engineering.
Stegman co-developed an irrigation scheduling method widely used by irrigators in North Dakota and surrounding states. He also served as a consultant to the U.S. Bureau of Reclamation on the Garrison Diversion Project and to a California irrigation district on Colorado River diversion issues.
