Leon F. Kneipp was the Assistant Chief of the United States Forest Service in charge of lands and land acquisition from 1920 to 1946. Kneipp was a member of the group that established the Department of Agriculture's Forest Service in 1905 and began his forest service career as a forest ranger in the territory of Arizona in 1900. From 1900 to 1905 he was part of the General Land Office administration of forest reserves where he dealt with the Oregon and Californian lands issue, and from 1906 to 1916 dealt with the Forest Homestead Act (1906), the Weeks Law (1911) and the Stockraising Homestead Law (1916). He became assistant chief in 1920 and was instrumental in acquiring approximately twenty million acres of natural forestland east of the Mississippi River. Kneipp also worked on public domain, range overstocking in WWI, the Helen Gahagan Douglas bill and the USFS and recreational parks. In this interview Kneipp discusses land-use policies, relationships between the interior and the forest service, his career, impressions of Gifford Pinchot, secretaries of Agriculture from 1900 to 1969, the USFS relationships with Congress, Presidents T. Roosevelt, Taft, Wilson, Harding, Hoover, and Eisenhower, the Ballinger-Pinchot controversy and the Secretary of Interior Harold Ickes. This interview is part of a group of interviews documenting the development of the U.S. Forest Service from 1900 to 1950.
