History of the Denver Zoo

The history of the Denver Zoo begins with the tale of an orphaned black bear who needed a home back in 1896.

That bear was named Billy Bryan and was actually gifted to the Mayor of Denver, Thomas S. McMurry.

Billy Bryan was placed in a cage in the city park and a park employee by the name of Alfred Hill was designated as Billy's caretaker.

Eventually, Hill actually became Denver Zoo’s first keeper and superintendent. Now 126 years later, the Denver Zoo is one of Colorado's most popular attractions.
