Sugar Ray Robinson was an American professional boxer. Frequently cited as the greatest boxer of all time, Robinson’s performances in the welterweight and middleweight divisions prompted sportswriters to create “pound for pound” rankings, where they compared fighters regardless of weight. Robinson was 85-0 as an amateur with 69 of those victories coming by way of knockout, 40 in the first round. He turned professional in 1940 at the age of 19 and by 1951 had a professional record of 128-1-2 with 84 knockouts. From 1943 to 1951 Robinson went on a 91-fight unbeaten streak, the third longest in professional boxing history. Renowned for his flamboyant lifestyle outside the ring, Robinson is credited with being the originator of the modern sports “entourage.” After his boxing career ended, Robinson attempted a career as an entertainer, but struggled, and was challenged financially until his death. Robinson was born on May 3, 1921 and died on April 12, 1989. In 2006, he was featured on a United States Postal Service commemorative stamp.
