Kornelia Ender is a former East German swimmer who at the 1976 Summer Olympics became the first woman swimmer to win four gold medals at a single Olympic Games, all in world record times. It was later proven that the East German team doctors had systematically administered steroids to their athletes. As an athlete who had exhibited symptoms of steroid use in 1976, strong suspicion was cast on the validity of Ender's accomplishments. Ender trained from a young age and won her first Olympic medals as a 13-year-old at the 1972 Olympics in Munich: three silver medals, including one in the individual 200 m individual medley, finishing behind Australia's Shane Gould. Over the following years she broke 32 world records in individual events, including the four at the Montreal Games. In 1991, she addressed the long-held suspicions about her physical condition at the 1976 Games, acknowledging that team doctors and coaches had given her numerous injections of drugs over the preceding months. Ender said that she did not know at the time, nor had she ever subsequently found out, exactly what the drugs were.
