Fifty years ago today Muhammad Ali gained the heavyweight world championship. The young Cassius Clay was brash, loud, cocky, and memorable. This fight, with the iconic photo of him standing over a prone Sonny Liston screaming “I shook up the world,” launched one of the most recognizable and famous sportsman of the 20th century. Ali’s name and face still carry huge weight and it is kindly ironic that a man who rose to fame with his fists and words is revered for his humanitarian work and his integrity. Fifty years after he told Liston he would “float like a butterfly and sting like a bee,” Ali’s name is that of a man who walks his talk.
