John Bushnell "Jack" Hanna is an American zookeeper, author and the founder of the Columbus Zoo and Aquarium. He was born on the 2nd of January, 1947 and in 2015 his current age is 70 years old.

He was born in Knoxville, Tennessee, the United States of America into a family of animal lovers. Born as the only child to a veterinarian father Dr. Roberts, he often used to volunteer and work with his dad in his small animal farm.

As a child, he went to study at the 'The Kiski School,' which was a boarding school for boys only, located in Saltsburg, Pennsylvania.

Upon graduating high school, he chose to study political science and business at the Muskingum College in Ohio. He was caught in his dorm where he had kept a duck and had also raised a donkey in the fraternity house, for which he was almost expelled.

He graduated college in 1969 but was married before that. He took over his parental farm after his father’s death and soon started his new business, along with his wife. He is an American by nationality and belongs to white ethnicity.

Jack is a tall man and has a very good height. He measures around 185 cm, which is 6 feet and an inch tall, a very good height indeed.

A slim and athletic person, he last had a body weight of 80 kg. And used to be a lot slimmer when he was young. You can see some of his pictures from the past when he used to have long hair and a charm ion his face.

Now that he has grown old, but still hasn’t lost his charisma. He has got some shirtless pictures as well, that can be found in the media where he is swimming with animals or taking care of them.

He is a good-hearted person and has always been working for the welfare of animals since his youth. He has never been in a gym and has got no tattoos on his body.

With some minor health problems due to his age, all the news that said he was dead has been proven false.

Although there is not much information regarding his dating life, he is a married man and has been in a long-term relationship with his wife, Suzi Egli.

The two of them came close with their love towards animals as Suzi used to work as a zookeeper too. They got married in 1968 and after 47 years of married life, haven’t got any chance to get divorced.

Their love towards each other has been strengthened with their three children, all of them being daughters: Suzanne Hanna, Julie Hanna and the smallest Kathleen Hanna.

With not much news of his girlfriends in the past of his romantic affairs with other women, he is not sexually gay, though.

Having toured around in search and rescue of animals from many countries, he has written many books about his adventures.

He has also been in some TV shows and movies, and you can find many interviews of his, as well as quotes in different websites.
