Jack Hanna is battling dementia, retiring at 74

The family of “Jungle Jack” Hanna, 74, has announced his retirement amid a diagnosis of dementia.

In a letter shared by Hanna’s family on Wednesday over social media, they confirmed that the beloved television personality and zookeeper had officially resigned his post as director emeritus of the Columbus Zoo and Aquarium in December, a role which he held for 42 years.

Daughters Kathaleen, Suzanne and Julie Hanna revealed his recent diagnosis of dementia, which the family now believes has progressed rapidly into Alzheimer’s disease.

“Sadly, Dad is no longer able to participate in public life as he used to, where people all over the world watched, learned and laughed alongside him,” his daughters wrote.
