Kieren Perkins (born 14 August 1973, Brisbane), is a former Australian professionale swimmer. One of the world's best-ever long-distance swimmers, he won two Olympic gold medals in 1992 and 1996 in the 1500-metre freestyle, and a silver medal in 2000.
Perkins began swimming regularly at age eight as part of his rehabilitation from a serious leg injury (after running through a plate glass window). At age 13 his potential became obvious, and with coach John Carew guiding him he won his first national title in 1989 and a Commonwealth title by 1990.Read more at Wikipedia
