Muhammad Ali, the legendary boxer who could hit much, much harder than you, passed away last Friday at age 74. He died of septic shock while being treated for a respiratory problem.

Ali’s nickname “the Greatest” kind of says it all. After more than two decades in the ring, he only lost a handful of fights. Your parents remember the “Rumble in the Jungle” match between Ali and his rival George Foreman, which Ali famously won using his "rope-a-dope tactic. Ali kept everyone on their toes outside the ring too. He changed his birth name from Cassius Clay when he joined the Nation of Islam, a black Islamic movement. Ali then defied the Vietnam draft, citing his religious beliefs - a hugely controversial move that got him banned from boxing for three years.

Ali retired from boxing in 1981, and was diagnosed with Parkinson’s disease a few years later. For decades, Parkinson’s limited his mobility and speech. But that didn’t stop him from doing a ton of humanitarian work and receiving the Medal of Freedom.

There’s a reason why you’ve seen athletes like Michael Jordan, and everyone else from President Obama to JK Rowling, paying tribute to Ali. He’s not just considered the best boxer of all time, but maybe the best athlete period.

Ali poses in 2002 on the roof of the Beverly Wilshire Hotel in Beverly Hills, California, where he was staying with his family. Using the chair helped steady the hands of Ali, who suffered from Parkinson's disease for three decades. "His hands were fascinating, punching so many opponents, so many times. The power of his fists, both literally and figuratively have left their mark in history," said photographer Rick Chapman. Rick Chapman
