(CNN) -- Legendary cornerman Angelo Dundee, the man who helped motivate Muhammad Ali and many other boxing champs, died Wednesday, a source close to Ali said. He was 90. Dundee died Wednesday in Florida from natural causes, Dundee's son Jimmy Dundee told CNN affiliate WFTS. Dundee, known for being a supreme motivator, was inducted in the International Boxing Hall of Fame in 1992. His biography on its website reads like a who's who list of boxing royalty. He was hired to be Ali's trainer and cornerman in 1960 back when the brash-talking, quick-jabbing boxer went by the name Cassius Clay. Dundee was there through Ali's historic name change, his brawls with George Foreman, "Smokin" Joe Frazier, Ken Norton and Leon Spinks.
