Muhammad Ali, who declared “I am the greatest” and proved it many times 
over, infuriating some and captivating countless more as he floated like
 a butterfly and stung like a bee on his way to winning the world 
heavyweight championship a record three times, becoming perhaps the most
 widely recognized person on the planet, died Friday in Phoenix. He was 
74. Mr. Ali had long suffered from Parkinson’s syndrome. The condition 
was understood to be a consequence of his boxing career.--
