The circus began as the “Carl Hagenbeck Circus” by [|Carl Hagenbeck] (1844-1913). Hagenbeck was an animal trainer who pioneered the use of rewards-based animal training as opposed to fear-based training. Meanwhile, [|Benjamin Wallace], a livery stable owner from [|Peru, Indiana], and his business partner, James Anderson, bought a circus in 1884 and created "The Great Wallace Show". Wallace bought out his partner in 1890 and formed the "B. E. Wallace Circus". In 1907, Wallace purchased the Carl Hagenbeck Circus and merged it with his circus. The circus became known as the Hagenbeck-Wallace circus at that time, even though Carl Hagenbeck protested. He sued to prohibit the use of his name but lost in court.
