The Ringling brothers (originally Rüngling) 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. Four brothers were born in McGregor, Iowa: Alf T., Charles, John and Henry, 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 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.
- Albert Carl "Al" Ringling (1852–1916). Albert divorced his wife in 1914 and died of Bright's disease at the age of 63 in Wisconsin.
- Augustus "Gus" Ringling (1852 – December 18, 1907). A founder of the circus, Augustus was largely self-educated. He died at age 55 from complications of various diseases at a sanatorium in New Orleans, where he had arrived two weeks earlier hoping the warmer climate would help his condition.
- Otto Ringling (born as William Henry Ringling, 1858–1911). Otto died April 2, 1911, at the home of his brother John, who lived on Fifth Avenue in Manhattan. He was in New York to see a show at Madison Square Garden.
- Alfred Theodore "Alf" Ringling (1861–1919). Alfred was a juggler. He had a son, Richard Ringling, and a daughter, Marjorie Joan Ringling, who was married to future United States Senator Jacob K. Javits from 1933 to 1936. His granddaughter, Mabel Ringling, married Richard Durant, an elephant trainer. 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. The property was also used as the winter quarters for his son Richard's circus, the R.T. Richards Circus. Alfred died in his 28-room New Jersey manor, three years after its completion, on October 21, 1919.
- Charles Edward Ringling (December 2, 1863 – December 3, 1926).

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.
