Joe Louis – the Brown Bomber Joseph Louis Barrow fought 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 26 championship fights and defeated 21 fighters. 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. Louis had the longest single reign as champion of any heavyweight boxer in history.
