Olympic record : 52.0 s - Glenn Hardin ( USA ), Los Angeles final , August 1, 1932. Hardin crossed the finish line in second place in this race. However, his time was recognized as the world record at the time, as the actual winner Bob Tisdall ( Ireland ) had illegally knocked over a hurdle during the race. Although Tisdall was Olympic champion, but his time was not recognized as a record.
