After a 32-year battle with Parkinson's disease, Muhammad Ali (Cassius Marcellus Clay, Jr.) has passed away at the age of 74. He had been in the hospital for a respiratory issue prior to his Friday death.

Nicknamed "The Greatest", Ali was involved in several historic boxing matches. Notable among these were the first Liston fight, three with rival Joe Frazier, and "The Rumble in the Jungle" with George Foreman, in which he regained titles he had been stripped of seven years earlier.

R.I.P. May you float like a butterfly eternal...
