(Born 1943) Her records themselves are impressive: 12 Grand Slam singles wins (including six Wimbledons) and 20 overall Wimbledon titles. King, however, is best known for advancing women's athletics. Her brother, Randy Moffitt, pitched for the San Francisco Giants; she herself reached a #4 world ranking in 1960 and turned pro eight years later. At the time, prize money for women was paltry, so she co-founded the Virginia Slims Tour, and in 1971 became the first female athlete to earn $100,000 in a year. Two years later, in front of over 30,000 at the Astrodome, she whipped Bobby Riggs in the 'Battle of the Sexes.' King retired in 1983, but not before winning a singles tournament at age 39.
