Jack Hanna

Jack Bushnell Hanna is an American retired zookeeper and director emeritus of the Columbus Zoo and Aquarium in Ohio. Commonly nicknamed "Jungle Jack", he was director of the zoo from 1978 to 1992, and is viewed as largely responsible for elevating its quality and reputation. His various television shows and media appearances, particularly with Johnny Carson, David Letterman, James Corden, Good Morning America, and Maury Povich have made him one of the most notable animal experts in the United States. A 2021 documentary, The Conservation Game, alleged that Hanna participated in the mistreatment and private trade of exotic and endangered animals.
