This year marks the 50th anniversary of Title IX of the Education Amendments of 1972, the law that opened all educational programs, including sports, to girls in the United States.

Tennis legend Billie Jean King has done more than any other athlete to make the promise of Title IX a reality. She also won a record 20 Wimbledon titles, 13 US titles, four French titles, and two in Australia between 1961 and 1979.
