Biographical or Historical Note

Research Associate (AMNH Entomology)

Cyril Franklin dos Passos was an amateur entomologist specializing in Lepidoptera, particularly butterflies. He was a research associate in the American Museum of Natural History's Dept. of Entomology for 50 years, beginning in 1936, and donated his collections of North American butterflies, over 65,000 specimens, to the museum. Dos Passos studied law, entering his family's firm, becoming a partner and successful businessman, and "retiring" at the age of thirty to pursue his own interests. He and his wife decided to study and collect Lepidoptera; dos Passos soon met with Dr. Frank E. Lutz, curator of the AMNH Dept. of Entomology, and began assisting him with the museum's collection of Lepidoptera. Dos Passos was instrumental in acquiring several collections for the museum, including those of J.D. Gunder, which he cataloged, and Thomas E. Bean. Discovering that there was no collection of photographs of type specimens of Nearctic Rhopalocera, dos Passos devised a portable photographic apparatus in order to record the specimens in other collections. In 1952, while continuing in his position at the AMNH, he was appointed a research associate at the Carnegie Institute. Dos Passos was also interested in the principles of zoological nomenclature, traveling widely in Europe, studying collections and attending conferences. He was a charter member of the Lepidopterists' Society, founded in 1947, and, with Lionel Paul Grey, developed a systematic catalog of the butterflies of North America. He accumulated an entomological library of historical sources, and published many articles on new and imperfectly known species. Dos Passos died in 1986
