Harry Lewis, was an American boxer, generally credited with holding the Welterweight Championship of the World from April 1908 to March 1911. He defeated "Young Joseph", the reigning Welterweight Champion of England in London on June 27, 1910, but was not credited with the British Welterweight championship as the fight was sanctioned as a World, and not English title. Boxing writer Nat Fleischer rated Lewis the sixth-greatest welterweight of all time. He was inducted into the International Jewish Sports Hall of Fame in 2002, and into the International Boxing Hall of Fame in 2008.

Frank Klaus was an American boxer from 1904 to 1918. Known as the Braddock Bearcat, Klaus claimed the vacant World Middleweight Championship in 1913 and was elected to the Ring Boxing Hall of Fame in 1974.
