The Ringling brothers (originally Rungeling) were seven American siblings of German and French descent who transformed their small touring company of performers into one of America's largest circuses in the late 19th and early 20th centuries. Born in McGregor, Iowa and raised in Baraboo, Wisconsin, they were the children of harness maker Heinrich Friedrich August Ringling (1826–1898), of Hanover, Germany, and Marie Salome Juliar (1833–1907), of Ostheim, in Alsace. They merged their Ringling Brothers Circus with America's other leading circus troupes, ultimately creating the Ringling Bros. and Barnum & Bailey Circus.

In 1956, North folded the big top and reincarnated the show for new arenas of the air-conditioned era.
