Records

(*) not ratified as he knocked over a hurdle
Morgan Taylor won the U.S. trials in a time of 52.6 but he also knocked over a hurdle, which was against the rules in force at that time. He did the same in the final of this competition so the time he set, again 52.6, was also not ratified as world record. As the second placed Erik Wilén used a similar style his 53.8 were also not accepted as world record but tolerated as Olympic record.
