International tennis star Billie Jean King (born 1943) did much to win equal treatment for women in sports.

Billie Jean (Moffit) King was born on November 22, 1943, in the southern California city of Long Beach. Both she and her brother, Randy, who would become a professional baseball player, excelled in athletics as children and were encouraged by their father, an engineer for a fire department.

Billie Jean developed an interest in tennis at an early age and saved money to buy her first racket. When she was 14 years old she won her first championship in a southern California tournament. The product of a working-class family, she soon found herself enmeshed in a country club sport. Despite her success on the court, the fact that tennis was oriented toward and dominated by men would prove a personal challenge to her in ensuing years.
