Anthony Conrad Nesty (born November 25, 1967) is a Surinamese former swimmer, the second black athlete to win an Olympic medal in swimming (after Enith Brigitha in Montreal 1976). Nesty established this historic milestone at the 1988 Summer Olympics in Seoul, South Korea. In the 100 m butterfly, Nesty out-touched then-favorite Matt Biondi by .01; Nesty finished in 53.00 and Biondi in 53.01. Nesty is the only Olympic medal winner from Suriname and after winning his Olympic gold medal, Nesty was unbeaten at the 100 meters butterfly for three years. Nesty attended the University of Florida.
Nesty's victory in Seoul was a momentous social and political event for Afro-Caribbeans. The Suriname government commemorated Nesty's gold-medal performance on a stamp and on gold and silver coins. A 25 Guilders bank note portraying the illustration of a butterfly swimmer was printed in his honor.
After his gold in Seoul, Nesty enjoyed a successful swimming career at the University of Florida, winning three consecutive NCAA Championships in the 100-yard butterfly (1990-92), one in the 200-yard butterfly (1990), and one as a member of the school's 400-yard medley relay (1991). He also won gold medals in the 100-meter butterfly at the Goodwill Games in 1990 and the FINA World Championships in 1991. Nesty attempted to defend his 1988 gold medal in the 100 fly at the 1992 Summer Olympics in Barcelona, but ended up with a third-place bronze medal.
Currently, Nesty is an assistant coach at the University of Florida. After serving as the men's assistant coach his first year, Nesty now is involved with both the men's and women's programs, but primarily works with the men's team.
