John Arthur ("Jack") Johnson (March 31, 1878 â€“ June 10, 1946), nicknamed the â€œGalveston Giantâ€, was an American boxer, the second African American Boxing Champion, and the first African American world heavyweight boxing champion (1908â€“1915).
Johnson was born in Galveston, Texas,
the third child and first son of Henry and Tina "Tiny" Johnson, former
slaves who worked at blue-collar jobs to raise six children and taught
them how to read and write. He dropped out of school after just five or
six years of education to get a job as a dock worker in Galveston.
