John Henry Lewis (1914–1974) was a hall of fame African American boxer who was the world Light Heavyweight champion from 1935 to 1939.
One interesting fact of his is that Lewis was managed by a gambler and racketeer of the 1930s: Gus Greenlee, a man who became very important to baseball's Negro Leagues as a commissioner and team owner.
Lewis began his professional career in 1928, beating Buster Grant by a four round decision, in Phoenix. His first 14 fights were in that city, until 1931, when he travelled to Prescott, to fight Sam Terrain on March 11. This proved to be a tragic event, as Terrain died as a consequence of the blows received during Lewis' fourth round knockout win.
Lewis had nine more wins in a row before facing future world Heavyweight champion, The Cinderella Man, James J. Braddock. He lost to Braddock in a 10th round decision, but, after two more wins, on November 16, 1932, he lost for the first time to fellow world Light Heavyweight champion Maxie Rosenbloom, by a decision in ten.
