Date	1 – 4 December 1956
Status	Olympic
Location	Olympic Park Swimming and Diving Stadium, Melbourne, Victoria
Participants	32 from 19 countries

In October 17-year-old Australian Murray Rose set the fastest time ever recorded for the distance in a 50 metre pool. This served as a prelude to a hugely successful Olympic Games for the teenager. Rose’s first victory of the three he obtained in Melbourne came in this event. Starting conservatively, Rose pulled away from the other swimmers over the second half of the race to win ahead of Tsuyoshi Yamanaka and George Breen. The three men would repeat their finishing positions in the 1500 m later in the Games. The winning time was narrowly outside Ford Konno‘s world record but when FINA changed their rules in 1957 to disallow times set in 25 m pools it became recognised as the world record. Rose went on to successfully defend his title four years later in Rome.
