East German Barbara Krause had won this event at the 1978 World Championships in a world record of 55.41 that still stood in July 1980. In the first round in Moscow she became the first woman to swim 100 metres in under 55 seconds, breaking her world record with 54.98. But Krause bettered that in the final, recording 54.79 for another world mark. Behind her came her teammates Caren Metschuck (silver) and Ines Diers (bronze) as the East German women swept the medals, as Metschuck and Diers became the second and fourth fastest performers of all-time. This was one of six swimming events in Moscow swept by the GDR women. The event had seen a medal sweep four times previously, by the United States in 1920, 1924, and 1968, and by Australia in 1956.
