#45: Billie Jean King: Tennis Superstar & Equality Activist
Billie Jean King is one of the most celebrated tennis players in history – for good reason. She won a total of 39 Grand Slam championships during the course of her career, and she broke many barriers for women in the world of tennis. She challenged the commonly held belief that women weren’t as strong as men, specifically by beating the infamous Bobby Riggs in a 1973 “Battle of the Sexes” tennis match.

Billie Jean King also pushed for equal prize money for men and women in the 1973 U.S. Open, which worked when she threatened to boycott the event. She is now 76 and has continued to be an advocate for women and LGBTQ+ athletes since her retirement in 1983. She was publicly outed in 1981, and has said that she never wants someone else to go through what she did.
