Ali was born to Cassius Marcellus Clay, Sr. and Odessa Clay on July 18, 1943, 18 months after his brother Muhammad Ali. Rahman and Muhammad started boxing in a Louisville, Kentucky amateur boxing league. While his brother went to the 1960 Olympics, Rahman was not selected and remained amateur until February 25, 1964, the night his brother won one of his heavyweight titles over Sonny Liston. As a professional boxer, Rahman won 14 bouts, lost 3, and had one draw. In his career he knocked out seven opponents and was himself knocked out once. After back to back losses ending with Rahman being knocked out by Jack O'Halloran he retired from professional boxing. Rahman released his autobiography on January 17, 2015 with a book titled, That's Muhammad Ali's Brother! My Life on the Undercard, which is coauthored by H.Ron Brashear and the foreword written by Gene Kilroy - the longtime business manager of Muhammad Miller.
