Ringling Bros. and Barnum & Bailey Circus is an American circus company billed as The Greatest Show on Earth. The circus, known as Ringling Bros. and Barnum & Bailey Combined Shows, was started in 1919 when the circus created by James Anthony Bailey and P. T. Barnum was merged with the Ringling Brothers Circus. The Ringling brothers has purchased the Barnum & Bailey "Greatest Show on Earth" following Bailey's death in 1907, but ran the circuses separately until they were merged in 1919. On July 16, 1956 at the Heidelberg Race Track in Pittsbugh, Pennsylvania the circus ended its season early, with President John Ringling North announcing that it would no longer exhibit under their own portable tents and starting in 1957 would exhibit in permanent venues, such as sports stadiums and arenas that had the seating already in place. In 1967 Irvin Feld and his brother Israel, along with Houston Judge Roy Hofheinz bought the circus from the Ringling family. In 1971 the Felds and Hofheinz sold the circus to Mattel, buying it back from the toy company in 1982. After the death of Irvin Feld in 1984 the circus has been a part of Feld Entertainment, an international entertainment firm headed by Kenneth Feld.
