Aldo Starker Leopold (October 22, 1913 – August 23, 1983) was an American author, forester, zoologist and conservationist. He also served as professor at the University of California, Berkeley for thirty years. Throughout his life, Leopold was active in numerous wildlife and conservation groups throughout the United States.
Born in Burlington, Iowa, in 1913, A. Starker Leopold was the oldest son of noted conservationist Aldo Leopold and Estella Bergere Leopold. His siblings—Luna, Carl, Estella, and Nina—all made contributions to the conservation movement. As a result of his father's employment by the United States Forest Service, Starker Leopold spent some of his youth in New Mexico; when his father began teaching at the University of Wisconsin, the family moved to Madison.
He received his B.S. from the University of Wisconsin in 1936, and then studied at the Yale Forestry School before transferring to the University of California, Berkeley, where he received his Ph.D. in Zoology in 1944. In 1938 he married Elizabeth Weiskotten; the couple had two children.
After working in Mexico for the Conservation Section of the Pan-American Union, Leopold returned to Berkeley in 1946 as Assistant Professor of Zoology and Conservation in the Museum of Vertebrate Zoology. He became professor in 1957. For three years (from 1960–1963) he was Assistant to the Berkeley Chancellor. In early 1967, he changed his affiliation to the School of Forestry and Conservation, where he was professor of Zoology and Forestry until his retirement as Professor Emeritus in 1978. He also served as Director of the Sagehen Creek Field Station from 1965 to 1978.
