Overview

The Columbus Zoo and Aquarium sits on the east bank of the O'Shaughnessy Reservoir on the Scioto River, in Liberty Township near Powell, on parkland the City of Columbus set aside when it built the O'Shaughnessy Dam. It opened in 1927 as Riverside Park, a 21-acre menagerie pushed into being by Columbus Dispatch publisher Harry P. Wolfe after a visit to the St. Louis Zoo. Renamed the Columbus Municipal Zoo in 1937, it passed back to city management around 1950 and in 1970 to the nonprofit Zoological Park Association. Colo, born there on December 22, 1956, was the first gorilla born in a zoo, and director Jack Hanna's television appearances from 1978 lifted attendance from about 360,000 to more than 1.4 million a year by 1992. Franklin County levies from 1985 paid for new regions, and the zoo lost its Association of Zoos and Aquariums accreditation in 2021 over financial mismanagement and animal transfers before regaining it in 2023.

Native American history

The 1880 History of Delaware County says Liberty Township held no Indian villages when white settlers arrived in 1801, but its forests were a favorite hunting ground. The township's settlers found the Olentangy crowded with Native people, mostly Wyandots, followed by Senecas, Delawares, Shawnees and others, according to the Goodrich family's account. On the Scioto side of the township, Otter Spring, where Mr. Stanbery lived in 1880, was a noted Indian camping place, and the Wyandot chief Leatherlips camped there on his annual hunt for many years. The trail from Sandusky to Chillicothe passed the spring. The same history records mounds and a walled earthen enclosure of nearly ten acres on a bluff of the Olentangy in Orange Township, just across the river from Liberty's southeast corner, and stone-lined graves on the Carpenter farm that it took to be Indian burials. Leatherlips, who had signed the Treaty of Greenville, was executed in 1810 by Wyandots sent by his brother Roundhead, on the Scioto at what is now Dublin, a few miles downstream. The 1880 history does not say where Otter Spring lay in relation to today's zoo grounds, and no archaeological site is recorded on the grounds themselves.

Stories

Six reindeer and a publisher

Harry P. Wolfe, publisher of The Columbus Dispatch, came home from a business trip to St. Louis with Mayor James Jay Thomas convinced that Columbus needed a zoo like the one he had seen there. The city said no in 1920, pleading lack of space, but people kept sending exotic animals as gifts, and they were kept at Franklin Park Conservatory. In December 1926 the Dispatch Christmas party featured six reindeer Wolfe had bought and shipped from Alaska, and afterward he gave them to the city with a long list of requirements for their care. By then the city had set aside parkland beside the new O'Shaughnessy Dam. Riverside Park opened there in 1927 on 21 acres, and the reindeer had a six-acre corner to themselves until the first building went up in 1932. (source)

Colo, the first zoo-born gorilla

Director Earl Davis had ordered his staff to keep the gorillas Baron Macombo and Millie Christina apart, afraid they would hurt each other. A young keeper, second-year veterinary student Warren Thomas, let them spend nights together anyway. On December 22, 1956, he found their baby still in the amniotic sac and revived her with mouth-to-mouth breathing. She was the first gorilla born in a zoo, a national contest named her Colo, for Columbus, Ohio, and five years passed before a second zoo gorilla was born anywhere. Colo had three children, and her son Oscar fathered the first surviving zoo-born gorilla twins in 1983. She died in her sleep in January 2017 at 60, the oldest gorilla on record. Thomas went on to direct the Los Angeles Zoo for 16 years. (source)

Jungle Jack

In 1978 the zoo's trustees and Columbus parks director Melvin B. Dodge hired Jack Hanna, a 31-year-old from Tennessee who had run a pet shop and petting zoo and a small zoo in Florida. Attendance was close to 360,000 a year. Hanna became a regular guest on Good Morning America, David Letterman's late-night show and Larry King's talk show, bringing animals onto national television and the zoo's name with them. By 1992 attendance topped 1.4 million, and that year he became Director Emeritus. He also starred in his own syndicated program, Jack Hanna's Animal Adventures, and his books included an autobiography, Monkeys on the Interstate. (source)

The restored 1914 Mangels-Illions carousel has been in Columbus since it was built. It was first located at Olentangy Park in the Clintonville area of Columbus and was moved in 1938 to Scioto Ranch Park, where Wyandot Lake later stood. After its restoration it took its first official spin at the zoo during Zoofari 2000, on June 17, 2000. At 5 p.m. on July 28, 2004, a boy from Upper Sandusky became its one millionth rider there. The zoo counted it as one of fewer than 200 survivors of the roughly 5,000 wooden carousels in the United States in the early twentieth century. (source)

Fluffy

In March 2007 a reticulated python named Fluffy came to the zoo on loan and went on display the next month. She was 24 feet long and weighed 300 pounds, and Guinness World Records listed her as the longest snake in captivity. Crowds came, and the new habitat built for her became her permanent home. She died on October 26, 2010, at 18, and a necropsy by the Ohio State University College of Veterinary Medicine found a mass on her ovary. (source)

Losing and regaining accreditation

In October 2021 the Association of Zoos and Aquariums, which had accredited the zoo since 1980, denied it accreditation. The association cited financial mismanagement and a record of repeated animal transfers to non-member facilities that supplied young animals, especially big cats, for entertainment. A documentary released that August, The Conservation Game, had alleged that Jack Hanna was involved in the exotic big-cat trade. The zoo, which had named Tom Schmid its new president the day before, appealed, arguing that its reforms were already in place; the association's president said more time was needed to let the changes take hold.
