A visionary sports promoter and the legal architect who helped ignite the revolution in women’s professional tennis, Lawrence 'Larry' King died on May 29, 2026, at his home in Grass Valley, California. He was 81. His life’s work was defined by a single afternoon in 1963 in the library at California State University, Los Angeles, where he met a young tennis player named Billie Jean Moffitt. In that quiet space, King experienced a profound realization regarding the systemic inequality facing women. He observed that despite being the best athlete in the school, Billie Jean was treated as a second-class citizen who could not even secure a grant because of her gender. This moment of clarity transformed a smart kid with little personal ambition into a man with a singular, lifelong pursuit: building the infrastructure for women's sports. As noted by Sportskeeda, King later remarked that helping Billie Jean change the world became his life.

This early commitment led King to the University of California, Berkeley School of Law, where he honed the legal mind that would eventually draft the blueprint for a social revolution. He became the strategic 'yin' to Billie Jean’s athletic 'yang,' working behind the scenes to turn radical ideas into legal realities. In 1971, he conceived the idea for a professional women's tour and helped organize the 'Original Nine' players to sign their historic one dollar contracts. His legal craftsmanship was most evident in a London hotel room at the Gloucester in 1973, where he drafted the original bylaws for the Women's Tennis Association during a meeting of sixty players. According to WTA Tennis, Billie Jean King described him as one of the unsung heroes of the era, noting that his love and commitment helped her navigate her career for over two decades.

King’s influence extended far beyond the courtroom and the boardroom. He was a central figure in promoting the 1973 'Battle of the Sexes' match, a cultural touchstone that brought his vision of gender equity to a global audience. His desire to innovate led to the co-founding of World TeamTennis in 1974, where he introduced co-ed rosters, multicolored courts, and no-ad scoring. He famously stated that he wanted to create a sport that was more like a party than a funeral. This festive, inclusive approach to athletics also informed his work co-founding womenSports magazine, the Women's Sports Foundation, and even Roller Hockey International. Even after his 1987 divorce from Billie Jean, he remained her close friend and business partner, a testament to the enduring bond formed in that college library decades earlier.

In his later years, King’s contributions received formal validation when he was honored with the inaugural Champions for Change Award by the WTA Foundation in 2024. This award recognized a lifetime of advocacy and the legal mind that enabled a social revolution. As reported by the Associated Press, King spent his final years in Northern California, having seen the world of sports transformed by the very structures he helped build. He is survived by his wife, Nancy Bolger, and their two children, Sky and Katie.

Larry King will be remembered as the quiet force who turned a sense of injustice into a global infrastructure. He did not seek the spotlight, yet he built the stage upon which others could stand as equals. His legacy is found in every professional contract signed by a female athlete and in the vibrant, inclusive atmosphere of the modern sporting event.
