May 25, 2020 marks 55 years since Muhammed Ali’s victory over Sonny Liston was captured in the now famous photo.
The photo, taken by Neil Leifer, was awarded the best image of the 20th century by Sports Illustrated.
The picture was taken after Ali put Liston on the canvas, with the fight ending after just two minutes and eight seconds.
“Get up and fight, sucker!” Ali cried at the moment the moment was captured by Leifer.
Liston did end up getting up off the canvas, but it was too late.
“The fight between Ali and Liston in Lewiston, Maine… I’ll never have a night like that again, ever,” Leifer said.
