There have always been acrobats and clowns, bareback riders and wild animal trainers. It took the genius of the seven Ringling Brothers to put them all under one tent. May 19 marks the first performance of the Ringling Brothers Circus in Baraboo, Wisconsin in 1884. Once the brothers purchased the competing Barnum and Bailey Circus, the Ringling Bros. Circus truly did become the greatest show on earth.
