Norman Selby (1872-1940), universally known by the pseudonym Charles "Kid" McCoy, was an American boxer active in the late 19th and early 20th centuries. Recognized for his cunning and unorthodox fighting style, his career culminated in winning the World Welterweight title. He is credited with inventing the "corkscrew punch" and with being the origin of the English expression "the real McCoy," a synonym for authenticity, derived from his undisputed skill in the ring. In addition to boxing, he pursued an acting career in Hollywood, appearing in several silent film productions. His turbulent life outside the ring ended tragically, but his sporting legacy remains significant. For his achievements and influence on the history of boxing, he was posthumously inducted into the International Boxing Hall of Fame in 1991, the highest honor for a boxer.
