John Douglas Lynch was an American herpetologist known for his work on Neotropical amphibians and reptiles, especially frogs. He studied at the University of Illinois and later earned a Ph.D. in zoology at the University of Kansas under William E. Duellman.
From 1969 to 1997 he taught at the University of Nebraska–Lincoln, and later worked at the Instituto de Ciencias Naturales of the Universidad Nacional de Colombia, where he served as a professor and curator of herpetology. Much of his research focused on the extraordinary frog diversity of Ecuador and Colombia, and he took part in the scientific description of more than 200 species.
Lynch spent decades doing fieldwork in remote areas and became a major figure in Colombian herpetology. Species and even whole genera have been named in his honor, a sign of how widely his work was respected in the scientific community.
