Celebrity Zookeeper Jack Hanna Diagnosed With Dementia

The 74-year-old Hanna was director of the Columbus Zoo from 1978 to 1992 and still serves as its director emeritus.

COLUMBUS, Ohio (AP) — Celebrity zookeeper and animal TV show host Jack Hanna has been diagnosed with dementia and will retire from public life, his family said.

In a news release Wednesday, his family added that it’s believed he now has Alzheimer’s disease that has quickly progressed in the last few months.

The 74-year-old Hanna was director of the Columbus Zoo from 1978 to 1992 and still serves as its director emeritus.

“Dad advocated for improved wildlife habitats and focused on connecting the community with animals,” the statement signed by his three daughters said. Hanna continued to be a spokesperson for the Ohio zoo until he retired in 2020.

Hanna is also well-known for his live animal demonstrations on talk shows hosted by Johnny Carson, David Letterman and James Corden, increasing the profile of the Columbus Zoo and leading to massive attendance increases over the years.

Hanna, who always wore khakis on every television appearance and in photos, hosted the popular syndicated TV show “Jack Hanna’s Animal Adventures” from 1993 to 2008. He also hosted “Jack Hanna’s Into the Wild,” which started in 2007, and “Jack Hanna’s Wild Countdown” until last year.

“While Dad’s health has deteriorated quickly, we can assure you that his great sense of humor continues to shine through,” the statement said. “And yes, he still wears his khakis at home.”

His family asked for privacy in light of COVID-19 restrictions.

“He has spent his life connecting people and wildlife because he has always believed that having people see and experience animals is key to engaging them in more impactful conversations,” his family said. “Even though Dad is no longer able to travel and work in the same way, we know that his infectious enthusiasm has touched many hearts and will continue to be his legacy.”

Top 10 Zoos Worldwide
Singapore Zoo – Singapore(01 of10)
Open Image Modal
Singapore Zoo is “open-concept,” meaning that the enclosures are separated not by fences or cages but moats that give an altogether more “in the wild” experience – for animals and visitors. The zoo has become world-famous as a home for our feathered friends. The specialties of the walk-in aviaries are the Birds of Paradise, the Bali Mynah, the Hyacinth Macaw and the Blue Throated Macaw. However, the flagship species – and visitor favorite – are the orangutans who lounge above your head as you leave the zoo. Just keep hold of your iPad. Search and compare cheap flights to Singapore.

San Diego Zoo – San Diego, USA(02 of10)

Visitors to the San Diego Zoo are typically surprised – and then immediately impressed – by the attraction’s cage-free setup. The SoCal zoo was one of the first in the world to build moats instead of bars, encouraging a more organic environment for the animals – and for spectators. Get a feel for the massive park on a five-mile-long monorail, then visit the adorable monkeys in the Lost Forest exhibit. Some of the rarest and most endangered primates dangle from tree canopies as visitors meet nearby flamingos, hippos, tigers and more. Search and compare cheap flights to San Diego.

Edinburgh Zoo – Edinburgh, Scotland(03 of10)

Tian Tian (the girl panda) and Yang Guang (the boy panda) left their Chengdu home and arrived in Scotland – to the sound of bagpipes – in December 2011. They are the first giant pandas to live in the United Kingdom for nearly 20 years, drawing around 70,000 panda lovers already – including Nicole Kidman and her daughters. The big hope is that they mate and have super-cute cubs. That would turn the 99-year-old, 1,000-animal Edinburgh Zoo into a stellar attraction. Search and compare cheap flights to Edinburgh.

Dubai Aquarium & Underwater Zoo – Dubai, United Arab Emirates(04 of10)

Like many of Dubai’s other attractions, the Aquarium and Underwater Zoo is a world-class show-stopper. It has even earned a place in the Guinness Book of Records for having the world’s largest acrylic panel. So far, so dull except for the fact that this panel is 32.8 meters wide, 8.3 meters high and holds 10 million liters of water. The aquarium/zoo has quickly become one of the best places to see sharks. There are seven new species there (Black Tip Shark, White Tip Shark, Spotted Bamboo Shark, Coral Cat Shark, Zebra Horned Shark, Wobbegong Shark and Leopard Shark) and it has the largest collection of Sand Tiger Sharks in the world.

The Belize Zoo and Tropical Education Center – Belize City, Belize (05 of10)

“The Best Little Zoo in the World” was founded nearly 30 years ago to provide sanctuary for wild animals used in a documentary about tropical forests. Today the zoo, located 29 miles west of Belize City, exhibits more than 150 animals native to Belize. A major draw is the represented five wildcat species found in the Central American country: jaguar, puma, ocelot, margay and jacuarundi. The Problem Jaguar Rehabilitation Program is just one of the zoo’s initiatives that help to promote conservation and awareness, and to protect Belize’s natural resources.

There’s nothing like escaping the big city to explore orphaned creatures and animals from around the globe. The eco-friendly escape was the first in the world to establish both a zoo education program and a predator-prey exhibition. Take a tour of Africa in the middle of New York: the African Plains exhibition is a second-best environment for giraffes, zebras and, of course, lions.

Remember Knut, the lovable polar bear cub who was raised by a zoo keeper at Berlin Zoo after his mother rejected him? He charmed the world, lending his likeness to a mountain of covetable merchandise before passing on at just four years. Now, happily, he has a new half-sister Anori whose playful frolicking is wowing visitors to the 24-hectare zoo in Wuppertal. Apart from Anori, the zoo also has the largest lion enclosure in a German zoo, an outdoor enclosure for orangutans and, somewhat unusual for a zoo, a large herd of elephants.

Lone Pine Koala Sanctuary – Brisbane, Australia(08 of10)

The first and largest koala sanctuary in the world was set up in 1927 and is home to more than 130 koalas. It’s one of the very few places where you can hold a koala (a hug and a photo costs about $20 AUD) and you can also feed kangaroos and the colorful lorikeets! Strict rules mean a koala can only be cuddled for up to 30 minutes each day and they get every third day off. There are lots of other native animals too – kangaroos, Tasmanian devils, wombats, echidnas, reptiles and a platypus. Search and compare cheap flights to Brisbane. (credit:Flickr:bareego)

Canada’s largest zoo is divided into seven geographic regions: Indo-Malaya, Africa, the Americas, Australasia, Eurasia, Canadian Domain and the Tundra Trek. In other words, the more than 5,000 animals – covering more than 500 species – is a strong representation of the planet’s creatures.
