Aldo Starker Leopold (1913-1983) was a wildlife biologist who made substantial contributions in the fields of ornithology,wildlife management and conservation, and public policy. The eldest son of noted ecologist Aldo Leopold (1887-1948) andEstella Bergere Leopold, he followed in his father's footsteps with his concern for wildlife management and environmentalconservation. A.S. Leopold grew up in Wisconsin and received his B.S. from the University of Wisconsin in 1936. Leopoldworked as a junior biologist with the United States Soil Erosion Service (1934-1935) and as a field biologist for the MissouriConservation Commission (1939-1944). He did graduate work in Forestry at Yale University and completed a Ph.D. inZoology at the University of California, Berkeley in 1944. Leopold's doctoral thesis was entitled The Nature of HeritableWildness in Turkeys. From 1944 to 1946, Leopold worked as Director of Field Research for the Conservation Section of thePan American Union. This would spark an interest in Mexico that would lead to the 1959 publication of one of Leopold'smost notable works, Wildlife in Mexico: The Game Birds and Mammals.

Leopold returned to Berkeley in 1946 as Assistant Professor of Zoology. He would continue as Professor of Zoology andForestry at UC Berkeley until his retirement in 1978. Leopold also served as Associate Director and Director of the Museumof Vertebrate Zoology on the University of California, Berkeley campus and Director of the Sagehen Creek Field Station(1965-1979). His scientific writings contributed greatly to knowledge of avian biology, and particularly of game birds.Leopold was an active member of many conservation societies, including the Nature Conservancy, the Sierra Club, TheWilderness Society, the National Wildlife Federation, and the California Academy of Sciences. Public service includedserving as consultant to the California Water Quality Control Board, the Missouri Conservation Department, and theTanzania National Parks. Leopold was also an appointee to the United States Marine Mammal Commission. During the1960s and 1970s, Leopold chaired commissions charged with making recommendations to the United States Secretary ofthe Interior about predator and rodent control, management of the national wildlife refuge system, and national parkwildlife, in general. Professional awards included election to the National Academy of Sciences, the Department of InteriorConservation Award, the Aldo Leopold Medal of The Wildlife Society, the Audubon Society Medal, the Browning Medal of theSmithsonian Institution, the Fellows Medal of the California Academy of Sciences, and a Distinguished Service Award fromthe American Institute of Biological Sciences.
