U.S. boxer, the first black to hold the title for the heavyweight championship of the world. Johnson's career was marked from the beginning by racial discrimination; until his match with Tommy Burns, he had a difficult time getting fights. Johnson won the heavyweight crown in 1908 by knocking out Burns and kept it until 1915, when he was knocked out by Jess Willard in 26 rounds. At the height of his career, Johnson was excoriated by the press for having twice married white women, and he further offended white supremacists by knocking out former champion James J. Jeffries, who was induced to come out of retirement as a "Great White Hope." In 1912 Johnson was convicted of violating the Mann Act for transporting his wife-to-be across state lines before their marriage. He was sentenced to a year in prison and was released on bond; he fled to Canada, made his way to Europe, and was a fugitive for seven years. He defended the championship three times in Paris before agreeing to fight Willard in Havana, Cuba. Some observers thought that Johnson, mistakenly believing that the charge against him would be dropped if he yielded the championship to a white man, deliberately lost to Willard. Johnson surrendered to U.S. authorities in 1920 to serve a one-year sentence. From 1897 to 1928, Johnson had 114 bouts, winning 80, 45 by knockouts
