The Navy Monkey (which was really a gorilla) was the first mascot. It was the favorite animal of U.S. Secretary of the Navy George Bancroft, who established the United States Naval Academy at Annapolis in 1845 during the administration of President James K. Polk. Bancroft's favorite animal, the monkey stayed the primary mascot -- along with a cat -- from 1847 to 1851. The first Bill the Goat appeared in 1893. Currently, Bill XXXIII reigns as the 36th mascot and is the 33rd goat to be named Bill. His backup is Bill XXXIV.
