Jack Bernstein was an American boxer given the birthname John Dodick. He became World Junior lightweight Champion, on May 30, 1923, against Johnny Dundee at the Coney Island Velodrome in Brooklyn. When he lost the title to Dundee on December 17, 1923, in a fifteen-round split decision at Madison Square Garden, many newspapers felt Bernstein clearly had the edge in the bout and should have retained the title.

Johnny "The Scotch Wop" Dundee was an American featherweight and the first world junior lightweight champion boxer who fought from 1910 until 1932. He was inducted into the Ring Magazine Hall of Fame in 1957 and the International Boxing Hall of Fame class of 1991.
