Ann Haymond Zwinger (1925–2014) was the author of many natural histories noted for detail and lyrical prose.
Ann Haymond Zwinger was born March 12, 1925, in Muncie, Indiana, the daughter of William and Ann Haymond. While young, she lived along the White River. She studied art history and was awarded two degrees, an A.B. in Arts in 1946 by Wellesley College with the designation "Wellesley College Scholar," now considered roughly equivalent to "cum laude," and an A.M. in Fine Arts by Indiana University in 1950. She married Herman H. Zwinger, a pilot, in 1952. She taught Southwest Studies and English at Colorado College.
She and co-author Beatrice Willard were finalists for the 1973 National Book Award in science for "Land Above the Trees." In 1976, she received the John Burroughs Memorial Association Gold Medal for a distinguished contribution in natural history, Run, River, Run. For the same book, she also received the Friends of American Writers Award for non-fiction.
