Which athlete competed in multiple events in the 1964 Tokyo Olympics and won six medals?

The correct athlete who competed in multiple events at the 1964 Tokyo Olympics and won six medals is not Ron Stein. Instead, the athlete associated with achieving such a remarkable feat during those Games was actually another individual.

In the 1964 Tokyo Olympics, the notable athlete who collected medals across multiple events was actually Mark Spitz. Spitz won a total of six gold medals in swimming, establishing himself as one of the standout competitors of the Olympics. The other athletes listed, including Ron Stein, did not achieve this level of success in relation to multievent participation and medal count during those specific Games.

To better understand the context: Ron Stein was involved in athletics but did not have a prominent record during the 1964 Olympics, whereas athletes like Billy Mills, known for his iconic win in the 10,000 meters, did not compete in multiple events or accumulate six medals either. Each of the athletes listed has their achievements and specialties, but only Mark Spitz showcased the level of success mentioned in the question.
