100 metres Butterfly, Women

Date23 – 24 July 1980
LocationPlavatelny basseyn, Sportivny kompleks Olimpiysky, Moskva
Participants24 from 17 countries

Mary T was not in Moscow, which made this event less than the best, despite the presence of the GDR women. Mary T. Meagher had set the world record of 59.26 in Austin, Texas in April 1980. In 1981 at the US Nationals she set a world record 57.93 that lasted for 18 years. In her absence the East German swept the medals, led by Caren Metschuck, who won in 1:00.42. She would win four medals in Moscow, adding golds in both relays, and a silver in the 100 freestyle.

Bronze medalist Christiane Knacke never swam much after 1980, her body ravaged by the effects of the drugs she had been given by the East German sporting system. In 1998 she joined other swimmers in suing former East German coaches and doctors, accusing them of ruining their health. One doctor, Rolf Gläser publically apologized to her and Knacke became the first Olympic athlete to offer to return her Olympic medal.
