Lucile Quarry Mann (1897-1986) was an editor and staff member of the National Zoological Park (NZP). She was born in Ann Arbor, Michigan, and received the B.A. in English from the University of Michigan in 1919. During World War I, she worked in Washington, D.C., with Military Intelligence. After the war, she was appointed assistant editor of the Bureau of Entomology of the United States Department of Agriculture. Lucile Quarry left the bureau in 1922 and became an editor for The Woman's Home Companion. In 1926 she married William M. Mann (1886-1960), an entomologist specializing in ants and termites.
After receiving the Sc.D. from Harvard University in 1915, William Mann collected insects in Fiji and the Solomon Islands as the Sheldon traveling fellow. From 1917 to 1925, he was a specialist in ants for the Bureau of Entomology and, during 1921-1922, participated in the Mulford Biological Exploration of the Amazon Basin. In 1925, he was appointed director of the National Zoological Park, and in 1926 led the Smithsonian Institution-Chrysler Expedition to Africa to collect animals for the NZP. Both the Manns traveled extensively for the NZP: to European zoos in 1929, 1938, and 1948, Central America in 1930, British Guiana in 1931, the National Geographic Society-Smithsonian Institution Expedition to the East Indies in 1937, Argentina in 1939, and the Firestone-Smithsonian Institution Expedition to Liberia in 1940. William Mann represented the Explorers Club and Lucile Mann the Society of Women Geographers in their travels.
Lucile Mann began work in the administrative offices of the NZP in 1951, continuing after William Mann's retirement in 1956 and death in 1960. She was primarily responsible for the NZP's annual report until her retirement in 1971.
Both the Manns published about their lives and interests. In addition to his many scientific monographs, William Mann published Wild Animals in and Out of the Zoo (1929) and Ant Hill Odyssey (1948). Lucile Mann published From Jungle to Zoo, Adventures of a Naturalist's Wife (1934), Tropical Aquarium Fishes (1934), and Friendly Animals, A Book of Unusual Pets (1935). The Manns had a wide circle of friends in many walks of life. William Mann was a circus fan as well as an opera enthusiast.
Lucile Mann kept tropical aquarium fishes and published about her hobby. William Mann founded the Vivarium Society, a group of individuals interested in keeping cold-blooded pets. Many animals born in the NZP were raised in the Manns' home across the street.
