The zoo, once known as The Jimmy Morgan Zoo, opened its doors with Monkey Island as its first official exhibit on April 2, 1955. The Jimmy Morgan Zoo operated as a quasi-private venture until city of Birmingham decided to assume responsibility in November 1955. In 1960, Bob Truett, a zoologist at the Lincoln Park Zoo in Chicago was hired as the first real zoo director. Truett petitioned the city and changed the name to the Birmingham Zoo. The city set an annual budget of $663,000 for its first year under city control.
