In June 1964 Kiki Caron of France bettered the world record of 1:08.6 and came to Tokyo as a slight favorite. She was expected to be challenged by America’s Ginny Duenkel, who had broken Caron’s mark in September by posting 1:08.3. Japan’s Satoko Tanaka was also highly considered, but she was better in the 200 backstroke, having set eight straight world records in that event from July 1960 to August 1963. Her 200 record had been broken just before the Tokyo Olympics by Cathy Ferguson, who was also entered in this event. In the final Ferguson, Caron and Duenkel were almost even at 50 metres. But Caron pulled ahead just after the turn, only to see Ferguson catch her near the end of the race and outtouch her to win the gold medal, 1:07.7 to 1:07.9. Duenkel held on for third, with Tanaka in fourth place.
