The collection includes correspondence, class notebooks, publications, extensive field and research notes, and photographs.
Biographical / Historical Notes
Alumnus and entomologist, Louis G. Gentner, was born in Portland, Oregon, in February 1892. Gentner received his B. S. from Oregon Agricultural College in 1915, his M. S. from the University of Wisconsin in 1918, and completed his doctorate at Oregon State College in 1953. He did his post-graduate work at Oregon State College in 1945 and 1946. After working as an entomologist in Wisconsin and Michigan, he became associate entomologist and assistant superintendent of the Southern Oregon Branch Experiment Station in Medford in 1930. Gentner's studies with alfalfa varieties led to the selection and naming of "Talent" alfalfa, now grown extensively for seed production exports. His work with beetles led to the elimination of the Klamath goat weed infestation on southern Oregon infested rangeland and enabling thousands of acres to be become viable again. Gentner retired from the station in 1962 and died July 16, 1980. Additional biographical information is included in the collection.
