Muhammad Ali

(born Cassius Marcellus Clay, Jr.) American former professional boxer, generally considered among the greatest heavyweights in the sport's history. A controversial and polarizing figure during his early career, Ali is today widely regarded for the skills he displayed in the ring plus the values he exemplified outside of it: religious freedom, racial justice and the triumph of principle over expedience.
