Presenting a half-dozen or more crowd-pleasing chimpanzees, they delighted European and U.S. audiences for three decades. After starring on such heralded European circuses as Knie, Krone, Williams, and Bertram Mills, their greatest acclaim came on Ringling Bros. and Barnum & Bailey. Featured in Ringling’s center ring for a remarkable 12 consecutive years and 14 years in all, they became one of the most popular animal presentations ever to appear on the Greatest Show on Earth. They also headlined many top American circuses.
