At a meet in Tokyo in July 1972 Japan’s Mayumi Aoki had set a world record in this event with 1:03.9. She was little known prior to that record but with no clear favorite in the event she seemed as good a bet as any. In the first semi-final, Hungary’s Andrea Gyarmati recorded 1:03.80 to better Aoki’s record. Aoki qualified second in the second semi. The early leader of the final was East Germany’s Roswitha Beier, who turned first, with six other swimmers in a blanket for second, while America’s best, Deena Deardurff, was last after a poor start. Beier maintained her lead until 10 metres from the wall when Aoki shot past to win the gold medal with another world record of 1:03.34. Beier held on for silver, with Gyarmati taking bronze. Deardurff closed quickly to take fourth, but she had dug too deep a hole for herself.
