Written in a lively, readable style, this book profiles two women who broke new ground in tennis. Alice Marble (1913-1990) became the first woman to play "power tennis, " and by 1939 had won several Wimbledon titles. Althea Gibson (1927- ) broke the racial "color line" in tennis by entering many previously white-only tournaments, and became the first black person to win both the U.S. Open and Wimbledon competitions.
