In which Olympic event did Floyd Patterson win his gold medal?

Floyd Patterson won his gold medal in the middleweight division at the 1952 Helsinki Olympics. This achievement was significant as he became the youngest heavyweight champion in boxing history later on, but his Olympic success came when he competed in the middleweight category. His victory at the Olympics showcased his exceptional skill and agility at that weight, helping him to establish a strong foundation for his professional boxing career. The other divisions listed do not correspond to Patterson's Olympic success, making middleweight the correct choice.
