Ricketts Brings the Circus to America
John Bill Ricketts, a Scottish-born equestrian who had trained in Astley's London circle, arrived in Philadelphia in 1792 and opened a riding school. Within months, he built a roofless wooden arena at the corner of Market and Twelfth Streets, fitted with a 42-foot ring filled with soil and sawdust.
On April 3, 1793, Ricketts staged the first American circus performance for roughly 800 spectators. The bill included his own riding tricks, his brother Francis on horseback, a rope-dancer named Spinacuta, and a clown called Mr. McDonald. President George Washington attended a performance on April 22 of the same year.
