Sugar Ray Robinson (born Walker Smith Jr.; May 3, 1921 – April 12, 1989) was an American professional boxer who competed from 1940 to 1965. 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. He is widely regarded as the greatest boxer of all time, and in 2002, Robinson was ranked number one on The Ring magazine's list of "80 Best Fighters of the Last 80 Years".
