Benjamin "Benny" Baruch J. Bass, known as "Little Fish", was an American boxer. He was born in Kyiv, Ukraine, with his family emigrating to the United States in 1906; choosing to settle in Philadelphia, Pennsylvania. Bass was world featherweight champion and world junior lightweight champion during his career. Statistical boxing website BoxRec lists Bass as the #17 ranked lightweight of all time. He was inducted into the International Jewish Sports Hall of Fame in 1994 and the International Boxing Hall of Fame in 2002. Strongly built with muscular shoulders, Bass's signature punch was a powerful left hook to the midsection, and he enjoyed fighting on the inside, a frequent requirement from his relative lack of reach.
