Margaret Court AO MBE (née Smith; born 16 July 1942), also known as Margaret Smith Court, is a retired world No. 1 professional tennis player. She is currently a Christian minister in Perth, Australia, but is best known for her sporting career, in which she amassed more major titles than any other player in history.
In 1970 Court became the first woman during the open era (and the second woman in history) to win the singles Grand Slam (all four major tournaments in the same calendar year). She won a record 24 of those titles, a record that still stands. She also won 19 women's doubles and 21 mixed doubles titles, giving her a record 64 major titles overall. She is the only woman to win the mixed doubles Grand Slam, which she accomplished twice.
