Dundee was instrumental in
Ali's victory over Henry Cooper
in London in 1963. Ali - then called Cassius Clay - was knocked down by Cooper but was saved by the bell.

It sums up the kind of man Angelo Dundee was that Ali and Sugar Ray Leonard would want to be with him for virtually their entire careers.
What was significant about Dundee is that you find trainers some of whom are brilliant in the gym but not so good on fight nights in the corner because they can't handle the occasion and the atmosphere.
But Angelo Dundee was equally adept in the gym or on big nights in the corner.
One of the all time greats and, as Bob Arum said, the greatest motivator of all time.
The trainer then made a tear in one of his fighter's gloves, delaying the start of the next round and allowing Ali to regain his senses. He went on to win the next round and the fight.
Dundee was always there for his protegee: when he joined the Black Muslims and became Muhammad Ali and when he defied the draft at the height of the Vietnam war, losing three-and-a-half years from his career.
Dundee gave him the nickname 'The Louisville Lip', and Ali wrote in the forward to Dundee's book: "Through all those days of controversy, and the many that followed, Angelo never got involved.
"He let me be exactly who I wanted to be, and he was loyal. That is the reason I love Angelo."
Dundee trained Leonard for many of his biggest fights, including bouts against Wilfred Benitez, Roberto Duran and Thomas Hearns, when he famously shouted, "You're blowing it, son. You're blowing it" to inspire his charge to victory by knockout.
Dundee was inducted into the International Boxing Hall of Fame in 1994 and attended Ali's 70th birthday party last month.
Promoter Bob Arum said he had been planning to bring Dundee to Las Vegas on 18 February for a charity gala headlined by Ali.
"He was wonderful. He was the whole package," Arum said. "Angelo was the greatest motivator of all time. No matter how bad things were, Angelo always put a positive spin on them. That's what Ali loved so much about him."

And he added: "Ali was this unbelievable figure, and a guy who symbolised an entire era of American culture and was idolised around the world.
"And through all those times, the person at his side was Dundee. For that, he will always be remembered."
American sportswriter Bert Sugar, ghostwriter of Dundee's autobiography, said: "He did things so subtly and he did them because he was Angelo Dundee and he was investing himself in his fighters.
"He would teach Ali how to do things and let Ali think it was his idea. He would finish Ali's poems for him when Ali couldn't come up with a line."

David Haye tweeted:
"R.I.P. Angelo Dundee. The Greatest Coach ever. I had the pleasure of spending time with him in Miami last year. What a true gentleman."
Dundee died surrounded by his family. "It was the way he wanted to go," Jimmy Dundee said. "He did everything he wanted to do.
"He was coming along good yesterday [Tuesday] and then he started to have breathing problems. My wife was with him at the time, thank God, and called and said he can't breathe.
"We all got over there. All the grandkids were there. He didn't want to go slowly."
