Bill Tilden

William Tatem Tilden II, known as Big Bill (1893 to 1953), was an American tennis player who dominated the game in the early 1920s. He was ranked the world number one amateur for six consecutive years from 1920 to 1925 and later the leading professional of the early 1930s. Tilden won fourteen major singles titles, ten of them Grand Slam events, including Wimbledon in 1920, the first American man to do so, and a joint record seven U.S. Championships. He won 138 of 192 tournaments in his twenty year amateur career before turning professional in 1930 and touring for fifteen more years. He often clashed with the United States Lawn Tennis Association over his amateur status.
