Ezzard Mack Charles (July 7, 1921 – May 28, 1975), was an American professional boxer who competed from 1940 to 1959. Known as "the Cincinnati Cobra", Charles was respected for his slick defense and precision, and is often regarded as the greatest light heavyweight of all time, and one of the greatest fighters pound for pound, having defeated numerous Hall of Fame fighters in three different weight classes. Charles was the world heavyweight champion from 1949 to 1951, and made eight successful title defenses in under two years. Wikipedia
