Muhammad Ali's death has struck a chord around the globe.

The boxing and social icon passed away Friday at the age of 74. President Obama, who penned an entire piece in 2010 for USA Today in explaining Ali's impact, released a lengthy statement on his passing, saying, in part, "Muhammad Ali was The Greatest. Period. If you just asked him, he'd tell you. He'd tell you he was the double greatest; that he'd 'handcuffed lightning, thrown thunder into jail.'"

Famed promoter Don King, who worked on some of Ali's most famous fights, also chimed in. “It’s a sad day for life, man," he said. I loved Muhammad Ali, he was my friend. Ali will never die. Like Martin Luther King his spirit will live on, he stood for the world.”

Those are merely a few of a score of acknowledgements pouring in for the fighter. Ali's death is being felt by people from the world of boxing and beyond, as expressed on social media.
