Patterson came back and knocked Johannson out in the fifth round of their rematch, with what many boxing historians have called the best punch ever in boxing, to become the first man ever to recover the world's undisputed heavyweight title.
Patterson further endeared himself with the people who had made Johansson their national hero, and when he went on a European exhibition tour after that rematch, he was greeted by Swedish fans, who were eager to shake hands, ask for autographs and take photos with Patterson everywhere he went during his stay there.
Patterson went on, but after losing a rematch to Ali for the North American Boxing Federation heavyweight title by technical knockout in seven, he retired for good in 1972.
