Louis Kaplan, nicknamed Kid Kaplan, was a professional Featherweight boxer. Having emigrated from Russia as a child, he began boxing as a teen and turned pro at 18. A busy fighter, he engaged in over 50 bouts in his first four years in the paid ranks. In 1923 he scored a 10-round win over future world lightweight champ Jimmy Goodrich. When featherweight champion Johnny Dundee vacated his title in 1924, a tournament was arranged to determine a successor. Kaplan knocked-out Angel Diaz in three rounds, defeated Bobby Garcia in 10-rounds and then halted Joe Lombardo in four rounds to advance to the finals. On January 2, 1925 he knocked out Danny Kramer in nine rounds at Madison Square Garden to become the new world champion. Kaplan was inducted into the International Jewish Sports Hall of Fame in 1986 and the International Boxing Hall of Fame in 2003.
