Arthur Ashe is best known for his career in what sport?

Arthur Robert Ashe Jr. (July 10, 1943 – February 6, 1993) was an American professional tennis player. He won three Grand Slam titles. Ashe was the first black player selected to the United States Davis Cup team and the only black man ever to win the singles title at Wimbledon, the US Open, and the Australian Open. He retired in 1980.

In the early 1980's, Ashe is believed to have contracted HIV from a blood transfusion he received during heart bypass surgery. Ashe publicly announced his illness in April 1992 and began working to educate others about HIV and AIDS. He founded the Arthur Ashe Foundation for the Defeat of AIDS and the Arthur Ashe Institute for Urban Health before his death from AIDS-related pneumonia on February 6, 1993.

Ashe remains the only black man to win the singles title at Wimbledon, the US Open, or Australian Open. He is one of only two men of black African ancestry to win any Grand Slam singles title, the other being France's Yannick Noah, who won the French Open in 1983. He also led the United States to victory for three consecutive years (1968–70) in the Davis Cup.

Two months before his death, he founded the Arthur Ashe Institute for Urban Health to help address issues of inadequate health care delivery and was named Sports Illustrated magazine's Sportsman of the Year. He also spent much of the last years of his life writing his memoir "Days of Grace", finishing the manuscript less than a week before his death.
