Johnson, Jack (John Arthur Johnson), 1878–1946, American boxer, b. Galveston, Tex., the son of two ex-slaves. Emerging from the battle royals (dehumanizing fights between blacks for the amusement of white patrons) of his youth, he defeated Tommy Burns in 1908 to become the worlds first African-American heavyweight champion. After an interracial marriage and his defeat of several white hopefuls, Johnson was convicted in 1913 under contrived circumstances for violation of a federal law. He fled to Europe and remained a champion in exile until he lost in a 1915 bout in Cuba, knocked out in the 26th round by Jess Willard. Upon his return to the United States in 1920, he served a year in prison.
