Ian Thorpe
Ian James Thorpe, is an Australian retired swimmer who specialised in freestyle, but also competed in backstroke and the individual medley. He has won five Olympic gold medals, the most won by any Australian along with fellow swimmer Emma McKeon. With three gold and two silver medals, Thorpe was the most successful athlete at the 2000 Summer Olympics, held in his hometown of Sydney. At the age of 14, Thorpe became the youngest male ever to represent Australia, and his victory in the 400 metre freestyle at the 1998 Perth World Championships made him the youngest-ever individual male World Champion. After that victory, Thorpe dominated the 400 m freestyle, winning the event at every Olympic, World, Commonwealth and Pan Pacific Swimming Championships until his break after the 2004 Olympics in Athens. At the 2001 World Aquatics Championships, he became the first person to win six gold medals in one World Championship.
