Guglielmo Papaleo was an American professional boxer, better known as Willie Pep who held the World Featherweight championship twice between the years of 1942 and 1950. Pep boxed a total of 1,956 rounds in the 241 bouts during his 26-year career, a considerable number of rounds and bouts even for a fighter of his era. His final record was 229–11–1 with 65 knockouts. Pep, known for his speed, finesse and elusiveness, is considered to be one of the best fighters of the 20th century; after his 199th win, Kid Campeche described his experience by saying, "Fighting Willie Pep is like trying to stamp out a grass fire." Pep was inducted into the International Boxing Hall of Fame in 1990. Pep was voted as the No. 1 featherweight of the 20th century by the Associated Press and ranked the No. 1 featherweight of all-time by the International Boxing Research Organization in 2005.
