Her 27 Grand Slam titles places her ninth on the all-time list: 13 in singles, 12 in women's doubles, and 2 in mixed doubles. She is the most recent player, male or female, to have held all four Grand Slam singles titles simultaneously and only the fifth woman in history to do so.

Arthur Robert Ashe, Jr. (July 10, 1943 – February 6, 1993) was a former World No. 1 professional tennis player, born and raised in Richmond, Virginia. During his career, he won three Grand Slam titles, putting him among the best ever from the United States. Ashe, an African American, was the first black player ever selected to the United States Davis Cup team and the only black man to ever win the singles title at Wimbledon, the US Open, or Australian Open. He is also remembered for his efforts to further social causes.

Born in Gum Spring, Virginia, to parents Arthur Ashe Sr. and Mattie Cordell Cunningham Ashe, Arthur and his younger brother, Johnnie, suffered a tragic loss when their mother died suddenly from heart related complications during routine surgery. Arthur Ashe first attended Maggie L. Walker High School, being coached by Ronald Charity, and later coached by Robert Walter Johnson. Tired of having to travel great distances to play Caucasian youths in segregated Richmond, Ashe accepted an offer from a St. Louis tennis official to move there and attend Sumner High School. Young Ashe was recognized by Sports Illustrated for his playing.
