Abe "The Newsboy" Hollandersky was an American professional boxer who won the Panamanian national Heavyweight Title when he defeated Californian Jack Ortega in nine rounds in Panama City on May 30, 1913. American congressmen, Naval personnel, and canal workers were among the crowd of nearly two thousand who watched Hollandersky gain victory over an opponent who outweighed him by over thirty-five pounds. The New York Times announced Hollandersky's best known win the following morning.

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.
