Arthur Hawthorne Carhart (1892–1978) was a US Forest Service official, writer and conservationist who inspired wilderness protection in the United States. He was one of the first to realize the importance of conservation and became a nationally recognized authority on conservation practices.
Carhart was born on September 18, 1892 in Mapleton, Iowa. He was the son of George W. and Ella Louise (Hawthorne) Carhart. His essay "The Downey Woodpecker" was published in The Women's Home Companion when he was eleven years old. In 1916, he was the first to graduate from Iowa State College with a Bachelor of Science degree in Landscape Design and City Planning. During his time at Iowa State College, he was a member of Acacia Fraternity. He worked for a Chicago landscaping architecture company until 1917, when he entered the United States Army for World War I. His education was put to use and he was made a lieutenant as a bacteriologist and public health officer in the Sanitary Corps at Camp Mead, Maryland. On August 16, 1918 he married Vera Amelia VanSickle. He left the Army after the war ended and moved to Denver, Colorado to work for the United States Forest Service. He worked for the Forest Service from 1919 till 1922 as a recreation engineer.
In 1919, Carhart surveyed a road in the White River National Forest, near Trappers Lake. Upon completion of the survey, he decided that the land should be preserved as wilderness. The Forest Service agreed, and the area was protected. The protection of Trappers Lake was the first of its kind in the history of the Forest Service. Carhart was the driving force behind recreational-use programs in national forests, first at San Isabel National Forest in Colorado and then at Superior National Forest in Minnesota.
In 1922 Federal funding was lost, and he left the Forest Service for private practice in land architecture and city planning as a partner in McCrary, Culley & Carhart. He sold his first book in 1928 and sold his interests in the firm to work full-time as a freelance writer in 1931. He made a living selling books, short stories and magazine articles for eight years. He then became the Colorado co-ordinator for the Federal Aid in Wildlife Restoration program, a position he held until 1943. He worked as the U.S. Office of Price Administration's information executive for the Rocky Mountain Region from 1944 to 1946. In 1946, he returned to writing. He wrote twenty-four books and over 4,000 articles. Carhart wrote historical novels, westerns, and books, stories and articles about forestry, wildlife management, and conservation. From 1960 to 1970, he served as a consultant to the Conservation Library Center At the Denver Public Library.
