John Arthur Johnson (March 31, 1878 – June 10, 1946), nicknamed the "Galveston Giant", was an American boxer who, at the height of the Jim Crow era, became the first black world heavyweight boxing champion (1908–1915). His 1910 fight against James J. Jeffries was dubbed the "fight of the century". Johnson defeated Jeffries, who was white, triggering dozens of race riots across the U.S. According to filmmaker Ken Burns, "for more than thirteen years, Jack Johnson was the most famous and the most notorious African American on Earth". He is widely regarded as one of the most influential boxers in history.
In 1912, Johnson opened a successful and luxurious "black and tan" (desegregated) restaurant and nightclub in Chicago, which in part was run by his wife, a white woman. Major newspapers of the time soon claimed that Johnson was attacked by the federal government only after he became famous as a black man married to a white woman, and was linked to other white women.
