Sugar Ray Robinson (born Walker Smith Jr., May 3, 1921 – April 12, 1989) was a 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. He was inducted into the International Boxing Hall of Fame in 1990. 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. Robinson held the world welterweight title from 1946 to 1951, and won the world middleweight title in the latter year. He retired in 1952, only to come back two and a half years later and regain the middleweight title in 1955. He then became the first boxer in history to win a divisional world championship five times, a feat he accomplished by defeating Carmen Basilio in 1958 to regain the middleweight championship. Robinson was named "fighter of the year" twice: first for his performances in 1942, then nine years and over 90 fights later, for his efforts in 1951. He defeated other Hall of Fame fighters such as Jake LaMotta, Carmen Basilio, Gene Fullmer, Carl 'Bobo' Olson, Henry Armstrong, Rocky Graziano and Kid Gavilan. Robinson engaged in 200 pro bouts, and his professional career lasted nearly 26 years.
Robinson was a fluid boxer who possessed power in both hands and a fast jab. In 1951 TIME said "Robinson's repertoire, thrown with equal speed and power by either hand, includes every standard punch from a bolo to a hook—and a few he makes up on the spur of the moment." Robinson stated that once a fighter gained a certain amount of skill their boxing technique became reflexive.
Robinson was named the greatest fighter of the 20th century by the Associated Press, and the greatest boxer in history by ESPN.com in 2007. The Ring magazine rated him the best "pound for pound" boxer of all-time in 1997, and its "Fighter of the Decade" for the 1950s. Muhammad Ali, who repeatedly called himself "The Greatest" throughout his career, ranked Robinson as the greatest boxer of all time. Other Hall of Fame boxers such as Joe Louis and Sugar Ray Leonard said the same.
