One of the most famous residents of that building was Jimmy the Chimp, who, at the time of his death at age 55 on September 17, 1985, was the oldest chimpanzee in captivity. When first opened, this building was true to the menagerie style of most zoos of the time, featuring dozens of unrelated species in a fairly compact space.
