Arguably the most important person in women’s tennis history, Billie Jean King was responsible for establishing the Women’s Tennis Association in 1973. Her strong character transcended the sport, and she was able to successfully advocate for equal pay regarding tournament prize money. If that wasn’t enough, BJK also won a total of 39 major titles across singles, doubles, and mixed doubles. In fact, she was considered the greatest rival to the all-time Grand Slam record holder Margaret Court.
