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). He is widely regarded as one of the most influential boxers in history, and his 1910 fight against James J. Jeffries was dubbed the "fight of the century". According to filmmaker Ken Burns, "for more than thirteen years, Jack Johnson was the most famous and the most notorious African-American on Earth". Transcending boxing, he became part of the culture and history of racism in the United States. In 1912, Johnson opened a successful and luxurious "black and tan" (desegregated) restaurant and nightclub, which in part was run by his wife, a white woman. Major newspapers of the time soon claimed that Johnson was attacked by the government only after he became famous as a black man married to a white woman, and was linked to other white women. Johnson was arrested on charges of violating the Mann Act—forbidding one to transport a woman across state lines for "immoral purposes"—a racially motivated charge that embroiled him in controversy for his relationships, including marriages, with white women. Sentenced to a year in prison, Johnson fled the country and fought boxing matches abroad for seven years until 1920 when he served his sentence at the federal penitentiary at Leavenworth. Johnson continued taking paying fights for many years, and operated several other businesses, including lucrative endorsement deals. He died in a car crash in 1946 at the age of 68. He is buried at Graceland Cemetery in Chicago. In 2018 Johnson was formally pardoned by U.S. president Donald Trump. Early life Johnson was born on March 31, 1878, the third child of nine born to Henry and Tina Johnson, former slaves who worked service jobs as a janitor and a dishwasher. His father had served as a civilian teamster of the Union's 38th Colored Infantry. He was described by his son as the "most perfect physical specimen that he had ever seen", although Henry had been left with an atrophied right leg from his service in the war. Growing up in Galveston, Texas, Johnson attended five years of school. As a young man, Johnson was frail, though, like all of his siblings, he was expected to work.
