Thornton T. Munger was the chief of Forest Management Research at the Pacific Northwest Forest and Range Experiment Station. Munger graduated from Yale School of Forestry in 1907 after developing an interest in forestry from his summers at Milford and the Gifford Pinchot estate as well as contacting foresters in Europe whose forest management had exceeded anything that was occurring in the United States at the time. After receiving his degree he passed the U.S. Forest Service test and was picked to go to Washington, D.C. to work for Raphael Zon's "Division of Silvics," which was the research branch of the agency. Munger remained in this position for only two months before he was shipped out to Portland, Oregon in 1908. While there he witnessed Gifford Pinchot's receipt of his letter of dismissal from President Taft in 1910. In 1924 he became the director of the Pacific Northwest Forest and Range Experiment Station where he dealt with staffing, timber taxation studies, timber surveys and New Deal programs. He returned to research in 1938 and became the chief of Forest Management Research and participated in activities in local conservation. In this interview, Munger discusses his education and early research, Yale, time in Silvics, various studies, land policies, timber sales, staff members, growth and yield studies, and New Deal programs. This interview is part of a group of interviews documenting forest history in the United States from 1900 to 1950.
