Source-derived summary

Jack Bushnell Hanna (born January 2, 1947) 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.

In 2019, Hanna was diagnosed with Alzheimer's disease, and subsequently stepped away from his official roles to be cared for by his family.

Early life

Hanna was born in Knoxville, Tennessee. He grew up on his family's farm and volunteered for the family veterinarian, Dr. Roberts, when he was 11. He attended The Kiski School, an all-boys boarding school in Saltsburg, Pennsylvania, for high school, graduating in 1965. He majored in business and political science at Muskingum College in New Concord, Ohio, where he kept ducks in his dorm room and a donkey in a shed behind his fraternity house (The M.A.C.E. Club). In his senior year, Hanna married Suzi, a cheerleader at Muskingum, and graduated in 1968.

Editorial summary

This brief starts where responsible research should: with the source description of “Jack Hanna” as american zoologist. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current lead gives the account dated anchors—1947, 1978, 1992, 2019—that can be checked directly. The linked authority record independently contributes the date 1947-01-02. The account is most persuasive where Jack, Hanna and American can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as american zoologist. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 25, 2026. The linked authority identifier is Q6112917. VIAF identifies the subject as 40933702. The Library of Congress control number is n88163278. 3 of 4 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1947, 1978, 1992 and 2019.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
