Omaha's Henry Doorly Zoo and Aquarium grew from Riverview Park Zoo, established on the site in 1894, into one of the United States' most ambitious zoological complexes. Renamed in 1963 after Margaret Hitchcock Doorly's gift honoring her husband, Henry Doorly, it became known for major indoor exhibits such as the Desert Dome, Kingdoms of the Night, and the Lied Jungle, as well as later expansions including African Grasslands. Conservation and research have been central to its identity, from black-footed ferret breeding to pioneering tiger reproductive science. Widely recognized for its scale and innovation, it remains a leading visitor attraction and conservation center in Omaha.
