Maurice Greene, American sprinter
Maurice Greene (born July 23, 1974) is an American former track and field sprinter who competed in the 100 meters and 200 meters. He is a former 100 m world record holder with a time of 9.79 seconds. During the height of his career (1997–2004) he won four Olympic medals and was a five-time World Champion. This included three golds at the 1999 World Championships, a feat which had previously only been achieved by Carl Lewis and Michael Johnson and has since been equaled by three others.

His career was affected by a number of injuries from 2001 onwards, although he won the 100 meters bronze and silver in the sprint relay at the 2004 Summer Olympics. Greene was also successful indoors: he was the 1999 Indoor World Champion, was the world record holder in the 60-meter dash for nearly 20 years and remains the joint-fastest man over 50 meters. He raced sparingly after an injury in 2005 and officially retired in 2008. Over his career, he made the third most sub-10-second runs (52) in the 100m, tied with Usain Bolt and only surpassed by Asafa Powell and Justin Gatlin.

Following his track career he has become an ambassador for the IAAF and a TV personality, appearing on Identity, Blind Date, and Dancing with the Stars. Most recently he volunteered as a track coach at University of California at Los Angeles (UCLA) for the 2012–2013 season.
