August "Gus" Ludwig Hormay Papers, 1900-1999

The papers document the life and career of Hormay. They include extensive outgoing and incoming correspondence, in addition to calendars and diaries that document his daily activities, 1930-1999. There are also copies of his numerous publications on range management topics. Other components of the collection include research files on several national forests in northern California, including Modoc National Forest, Lassen National Forest, and Plumas National Forest, 1931-1993. The papers contain especially rich documentation of Lassen National Forest and the experimental forests and ranges therein, such as Blacks Mountain Experimental Forest, Burgess Spring Experimental Range, and the Harvey Valley Grazing Allotment. Extensive documentation exists for numerous grazing allotments and rangelands throughout the intermountain and Trans-Mississippi West analyzed and visited by Hormay, primarily 1965-1977. Hormay also completed hundreds of experiments concerned with the reproduction and germination of bitterbrush (Purshia tridentata), 1942-1979. A relatively small portion of the collection documents the family life of Hormay, including photographs of his family and his home in San Francisco. Photographs and transparencies extensively document the work of Hormay in the national forests of northeastern California and rangelands throughout the western region of the United States.
