Biographical Note

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.

Content Description

The Gentner Papers document the entomological research conducted by Gentner, primarily on flea beetles, as well as his professional activities and undergraduate and graduate education. The collection includes correspondence, class notebooks, publications, extensive field and research notes, and photographs.

Administrative Information

Arrangement :

This collection is organized into six series: I. Biographical Information; II. Correspondence; III. School Records and Materials; IV. Entomology Field Work and Research Notes; V. Organizations; and VI. Photographs.

Custodial History :  

A portion of these papers were donated directly to the University Archives by Louis Gentner's daughter, Laura Gentner Dunwald, in December 1985. Other materials were donated to the Horner Museum by the OSU Archives in 1985 and were subsequently returned to the Archives in August 1996. It is likely that they were also donated by Laura Gentner Dunwald. A subsequent addition to the collection was transferred from the Entomology Department in 2001.

Related Materials :  

Other materials relating to the Entomology Department can be found in the Agricultural Experiment Station (RG 025) and Entomology Department (RG 027) Records. Other entomological collections held by the OSU Archives are the papers of Ralph Berry, John D. Lattin, Merton Lane, Charles H. Martin, James McIver, Hugh E. Morrison, Paul W. Oman, Paul Ritcher, Robert G. Rosenstiel, and Herman A. Scullen and the A.B. Cordley Entomological and Horticultural Scrapbook. Materials relating to Gentner's research on flea beetles are held by the Smithsonian Institution Archives ( Louis G. Gentner Papers, RU 7341).
