Billie Jean (Moffitt) King was born on November 22, 1943, in the southern California city of Long Beach. She was the first of Willard and Betty Moffitt's two children. Her father was an engineer for the fire department, and her mother was a receptionist at a medical center. Both she and her brother, Randy, who would become a professional baseball player, excelled in athletics as children and were encouraged by their parents. At fire department picnics, her father's coworkers always wanted Billie Jean to play on their softball team.
