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.
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 lived modestly until his death in 1989. In 2006, he was featured on a commemorative stamp by the United States Postal Service.
After retiring as a boxer
In his autobiography Robinson states that by 1965 he was broke, having spent all of the $4 million in earnings he made inside and out of the ring in his career. A month after his last fight, Robinson was honored with a Sugar Ray Robinson Night on December 10, 1965 in New York's Madison Square Garden. During the ceremony, he was honored with a massive trophy. However, there was not a piece of furniture in his small Manhattan apartment with legs strong enough to support it. Robinson was elected to the International Boxing Hall of Fame in 1967, two years after he retired. Very few remember that he participated, impersonating a retired boxer, in two episodes (The Contenders, part 1 and 2) of the third season of Mission Impossible, in 1968. In 1966, he portrayed Biff Bower, an ex-boxer turned club owner and trumpet player in the Irwin Allen series "Land of the Giants" episode, "Giants and All That Jazz." In 1969 he founded the Sugar Ray Robinson Youth Foundation for inner-city Los Angeles area. The foundation does not sponsor a boxing program. He was diagnosed with diabetes mellitus that was treated with insulin. In Robinson's last years, he was diagnosed with Alzheimer's disease. He died in Los Angeles at the age of 67 and was interred in the Inglewood Park Cemetery, Inglewood, California.
