Cavill family
The Cavill family of Australia is known for its significant contributions to the development of the sport of swimming.
Prominent family members in the sport include Frederick Cavill (1839–1927), sons Ernest Cavill (1868–1935), Charles Claude Cavill (1870–1897), Percy Frederick Cavill (1875–1940), Arthur Rowland Channel (Tums) Cavill (1877–1914), who is credited by sports journalist W.F. Corbett with originating the Australian crawl stroke, which now predominates in "freestyle" swimming races; and Sydney St. Leonards Cavill ("Sid") (1881–1945), was one of the originators of the butterfly arm stroke. Youngest son Richmond (Dick) Theophilus Cavill (1884–1938) was the first to use the crawl in a competition, winning 100 yards State championship in 1899; and in England, in 1902, he was the first to swim 100 yards in under a minute.
Six members of the family were jointly inducted into the International Swimming Hall of Fame in 1970.
The three daughters, Madeline, Fredda and Alice Cavill were all accomplished swimmers and swimming instructors.
Fredda Cavill's son Dick Eve won gold at the 1924 Summer Olympics in the plain high diving, becoming the first Australian Olympic diver to win gold.
