Jack “The Giant” O’Halloran was born in Philadelphia and though ending up in Runnemede, NJ, for the most part before returning to Philadelphia now at age 73.

He defeated Williams and Lewis. He also defeated the brother of Muhammad Ali Rahman Ali. He defeated world title challengers Terry Daniels and Manuel Ramos.
“Ali called me up and said you are fighting my brother Rahman. He is embarrassing me so I want you to make sure he never fights again”. O’Halloran knocked him out in the 8th round in San Diego. It was the last time the 14-3-1 Ali ever fought again and the first time he was ever knocked out.
O’Halloran came close to fighting Muhammad Ali 3 or 4 times. He claims “Smokin” Joe Frazier would not spar with him or contender Leotis Martin. When I took the Lewis fight on short notice. When his trainer Manny Steward came into the gym and saw me spar I heard him say “I think we are in trouble” and they were. He said the hardest he was ever hit was by Cleveland “Big Cat” Williams though he went on to win a decision.
