1957: Althea Gibson won the women's singles title at Wimbledon. She was the first African American to win a tennis championship at the historic All England Lawn Tennis & Croquet Club. Born on August 25, 1927, in Silver, South Carolina, Gibson grew up in New York's Harlem, a haven for black artists, musicians, and intellectuals in the 1920s. She took her first tennis lesson at the age of thirteen after receiving a tennis racket as a gift. A year later, she won her first tournament in a match sponsored by the American Tennis Association, a mainly African-American league. (Source: Library of Congress)
