Joseph Louis Barrow (May 13, 1914 – April 12, 1981) was an American professional boxer who competed from 1934 to 1951. Nicknamed the Brown Bomber, Louis is widely regarded as one of the greatest and most influential boxers of all time. He reigned as the world heavyweight champion from 1937 to 1949, during which he participated in 27 championship fights. The 27th fight, against Ezzard Charles in 1950, was a challenge for Charles' heavyweight title and so is not included in Louis' reign. He was victorious in 25 consecutive title defenses. In 2005, Louis was ranked as the best heavyweight of all time by the International Boxing Research Organization, and was ranked number one on The Ring magazine's list of the "100 greatest punchers of all time". Louis had the longest single reign as champion of any heavyweight boxer in history. He has been ranked as the world's best heavyweight by BoxRec 11 times (the second most in history, only behind Muhammad Ali) and has been placed within ten best 15 times. Six of his victorious fights were rated 5-Star by BoxRec.
