Jack Sharkey Jack Sharkey (Lithuanian: "Juozas Povilas Žukauskas" , October 26, 1902 – August 17, 1994) was an American world heavyweight boxing champion. He was born Joseph Paul Zukauskas (his birth surname is sometimes given as Cukoschay), the son of Lithuanian immigrants, in Binghamton, New York but moved to Boston, Massachusetts as a young man. Sources report little of his early life until, at the outset of the First World War, teenaged Joseph repeatedly tried to enlist in the Navy. Turned down because of his age, he was not able to enlist until after the end of the war.
Jack Johnson (boxer) John Arthur "Jack" 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 African American world heavyweight boxing champion (1908–1915). Johnson went on to become one of the most dominant champions of his time, and remains a significant historical figure in heavyweight boxing history, with his 1910 fight against James J. Jeffries being dubbed the "fight of the century." Johnson was faced with much controversy when he was charged with violating the Mann Act in 1912, even though there was an obvious lack of evidence and the charge was largely racially based. In a documentary about his life, Ken Burns notes that "for more than thirteen years, Jack Johnson was the most famous and the most notorious African-American on Earth".
