Helen Wills Moody (left) dominated women's tennis from 1926 until the outbreak of World War II. She won eight singles finals at Wimbledon and seven US championships. Her great rivalry with Helen Jacobs drove her to continue to play during the 1938 Wimbledon final, despite being severly handicapped by injury.
