Born in Dayton, Ohio, on September 6, 1930, he developed an early interest in natural history and began building that passion while still in school. He went on to become an American zoologist and herpetologist best known for his work on amphibians.
He joined the University of Kansas in 1959 as Curator of Herpetology and later became curator emeritus and professor emeritus. Over many years, he carried out extensive field studies in Mexico, Central America, and South America, and became especially influential in the study of Neotropical amphibians.
Duellman was widely respected for both his research and his books, including major works on amphibian biology. He died on February 25, 2022, and is remembered as one of the central figures in herpetology of his era.
