The Rieffenach family were circus performers who specialized in a bareback riding act that performed in Europe and the United States during the first half of the 20th century. Family members, daughters Maria (Mitzi) Rieffenach and Rose (Rosie) Rieffenach, were inducted into the Circus Hall of Fame in 1970. The Rieffenach Family Equestrian Act originated from the marriage of the mother Maria Enders of the Hungarian Circus Enders, and Simon Rieffenach Sr. The family performed their horseback riding act with the Sarrasani Circus in Europe from 1905 and were with the German Circus Carl Hagenbeck in 1921. The Rieffenach Family Riding Act came to the United States in 1922 after being booked to perform for the Ringling Bros. and Barnum & Bailey Circus. The Rieffenach Family Act was with Ringling Brothers for sixteen years through 1937. In her memoir, Tiny Kline, the famous circus acrobat, stated: "The Rieffenachs' riding act had been the feature in the center ring of the Big Show since their arrival from Austria". In 1939 the Rieffenachs went on the Cole Bros. Circus, performing through 1942 after which time the act was disbanded. One son, James Rieffenach, continued riding with the Poodles Hanneford Act, while the other members of the act retired. James died of a heart attack in 1945 while still performing with the Cole Bros. Circus.
