Adolph Kiefer was already clearly ahead at the halfway point, and was never threatened during the race. He broke the Olympic record and finished ahead of fellow American Al Vande Weghe who moved past Kiyokawa in the closing stages. The race was watched by a relatively small crowd, the result of bad weather and a clash with the handball final.
First 3 from each Semi and Best 4th (Kiichi Yoshida, Japan) advanced to Final.

Masaji Kiyokowa returned to defend his title but the four years since Los Angeles had seen the emergence of Adolph Kiefer. Kiefer’s father had been a swimming instructor in the German army and Keifer was to arrive in his father’s homeland as the world record holder.
