Muhammad Ali, world heavyweight champion, punches speed bag on Sept. 29, 1975 at the Folk Art Center in Manila, Philippines as he prepares his title fight on October 1 with Joe Frazier
The legendary boxer had been suffering from respiratory symptoms which were linked to Parkinson's Disease.
Since he died, prominent artists, politicians, and public figures - from Barack Obama and Donald Trump to Sean Diddy Combs and Hamilton auteur Lin Manuel-Miranda - have paid homage to the boxing great.
Here's what some are saying:
