In 1940, Challedon was a talented racehorse who resided in Walkersville, MD. Jack Warner of Warner Studio placed a bet based on a tip from his friends in Frederick. His bet paid off and to thank his friends, he provided air-conditioning to the Tivoli Theater, now known as the Weinberg Center for the Arts. This was the first air-conditioned building in Frederick.
A picture of Challedon welcomes guests in the lobby to this day.
