Michael Fred Phelps (born June 30, 1985) is an American swimmer. He has won 14 career Olympic gold medals, the most by any Olympian. By the end of 2008, he held seven world records in swimming.

Phelps holds the record for the most gold medals won at a single Olympics with the eight golds he won at the 2008 Olympic Games. With this record, he surpassed American Mark Spitz, who was also a swimmer and had held the previous gold medal total with the seven that he won at the 1972 Munich Olympic Games.

Overall, Phelps has won 16 Olympic medals: six gold and two bronze at Athens in 2004, and eight gold at Beijing in 2008. In winning these medals, he has twice equaled Soviet gymnast Alexander Dityatin's record of eight medals (of any type) at a single Olympics; Dityatin garnered eight at the 1980 Summer Olympics, while Phelps won eight medals at both the 2004 Summer Olympics and the 2008 Summer Olympics. Out of his eight gold medals from Beijing, five were won in individual events, tying the record for individual gold medals at a single Games originally set by Eric Heiden in the 1980 Winter Olympics and equaled by Vitaly Scherbo at the 1992 Summer Games. Phelps ranks second in total career Olympic medals, after Soviet gymnast Larissa Latynina, who won a total of 18 medals (nine gold) spanning three Olympic Games.

Phelps's international titles, along with his various world records, have resulted in him being awarded the World Swimmer of the Year Award in 2003, 2004, 2006, 2007 and 2008 and American Swimmer of the Year Award in 2001, 2002, 2003, 2004, 2006, 2007 and 2008. Phelps has won a total of 48 career medals thus far: 40 gold, six silvers and two bronze. This includes all of the Championships in which he has competed: The Olympics, the World Championships, and the Pan Pacific Championships. In 2008 Phelps won Sports Illustrated magazine "Sportsman of the Year" award. (via Wikipedia)
