Circus History
Benjamin Wallace, a livery stable owner from Peru, Indiana joined with his partner, James
Anderson, and bought a circus. They presented their first show in 1884. The show
eventually traveled under the name of The Great Wallace Show. In 1890, Wallace bought out
his partner, and in 1891 established the Wallace winter quarters on land purchased from
Chief Godfroy. In 1907 the Carl Hagenbeck Circus became the property of Wallace and thus
came into being the Hagenbeck-Wallace Circus. After buying out the other partners, John
Talbot was Wallace's only partner. In 1913 (the year of Peru's largest flood),
Wallace suffered greatly financially and otherwise. He sold the show while it was on the
road maintaining ownership of all the land & buildings. Members of the syndicate
purchasing the circus were C.E. Cory, John O. Talbot and Edward W. Ballard. The American
Circus Corporation was formed in 1921 with Jerry Mugivan, Bert Bowers & Ed Ballard as
directors. During the 1920s Peru became!
known on the maps as the "Circus City". John Ringling purchased the entire
A.C.C. holdings, including the Peru quarters and farms in September 1929. In November
1941, 126 circus wagons were burned, effectively ending the old circus era in Miami
County. Many famous performers gave their talents to the circuses and called Peru home.
Mickey King & husband, Antoinette & Art Concello, Emmett Kelly, Otto Griebling,
Terrell Jacobs, Clyde Beatty, Tom Mix, Ken Manard , The Hodginis, and many others were all
a part of Peru's golden age of the circus. The old winter quarters is now the home of
the International Circus Hall of Fame. Circus performances are conducted there throughout
the summer months. In July Peru hosts the Circus City Festival, a week of circus
performances by the young people of the community. Both of these events keep alive the
rich circus heritage of the area.
