Althea Gibson (August 25, 1927 – September 28, 2003) was an American tennis player and professional golfer, and the first black athlete of either gender to cross the color line of international tennis. In 1956 she became the first person of color to win a Grand Slam title (the French Open). The following year she won both Wimbledon and the U.S. Nationals (precursor of the U.S. Open), then won both again in 1958, and was voted Female Athlete of the Year by the Associated Press in both years. In all she won 11 Grand Slam tournaments, including six doubles titles, and was inducted into the International Tennis Hall of Fame and the International Women's Sports Hall of Fame. "She is one of the greatest players who ever lived," said Robert Ryland, a tennis contemporary and former coach of Venus and Serena Williams. "Martina couldn't touch her. I think she'd beat the Williams sisters." In the early 1960s she also became the first black player to compete on the women's professional golf tour.
