The Ringling brothers (originally Rüngling) were five American siblings who transformed their small touring company of performers into one of the largest circuses in the United States during the late 19th and early 20th centuries. Four brothers were born in McGregor, Iowa: Alfred T., Charles, John and Henry William, and the family lived in McGregor for twelve years, from 1860 until 1872. The Ringling family then moved to Prairie du Chien, Wisconsin, and finally settled in Baraboo, Wisconsin, in 1875. They were of German and French descent, the children of harness maker Heinrich Friedrich August Ringling (1826–1898) of Hanover, and Marie Salome Juliar (1833–1907) of Ostheim, in Alsace. While there were seven Ringling brothers, Alfred, Charles, John, Al and Otto Ringling were the main brothers in charge of the circus shows. All of the brothers were Freemasons. In 1919, they merged their Ringling Brothers Circus with America's other leading circus troupe, Barnum and Bailey, ultimately creating the Ringling Bros. and Barnum & Bailey Circus, which operated for 98 years, until 2017.

In 1916, Alfred took up residence in Petersburg, New Jersey, now known as Oak Ridge, where he was responsible for the creation of Lake Swannanoa, the body of water that would later become the center point of the Lake Swannanoa lake community.

John Ringling North, 81, flamboyant, fast-talking showman who from 1937 to '43 and from 1947 to '67 ran "The Greatest Show on Earth," the Ringling Bros. and Barnum & Bailey Circus, started by his five uncles in 1884; of a stroke; in Brussels. North took over the debt-spangled show after the death of his last uncle, John Ringling, and modernized it with such attractions as Gargantua the Great, the "vehemently vicious" 550-lb. gorilla that drew more than 40 million circusgoers. In 1956, North folded the big top and reincarnated the show for new arenas of the air-conditioned era.
