Muhammad Ali, perhaps the greatest sportsman to grace the international stage, received the Liberty Medal on Thursday at Philadelphia's National Constitution Center.
The honor is bestowed on those who fight for humanitarian causes, civil rights and religious freedom. A $100,000 cash prize is awarded to the recipient.
Ali, now 70 and stricken with Parkinson's disease, did not speak during the ceremony. His wife, Lonnie, and daughter, Laila, spoke on his behalf.
"You know, my father loves people and people love my father, and I learned that at a very young age, as people would always come up to him wherever we went," his daughter said. "My father has always lived his life to make this world better for others."
