Four gold medals at a single Olympic Games were secured by Kornelia Ender in 1976, marking her as the first female swimmer to achieve this feat in world record times. Born in Plauen in 1958, the German athlete transitioned from a promising teenage competitor in Munich to a dominant international figure during the mid-1970s.
Olympic Progression
Ender began her Olympic career as a 13-year-old at the 1972 Munich Games, where she collected three silver medals. Among these was a second-place finish in the 200 m individual medley behind Shane Gould of Australia. Her career trajectory shifted rapidly over the following years, during which she broke 32 world records in individual events.

The validity of Ender's performance in 1976 faced intense scrutiny due to her physical changes, such as a deep voice and increased muscle mass. In 1991, she confirmed that team doctors and coaches had administered injections without her knowledge. She stated that staff claimed these drugs were for regeneration and recuperation. In 1977, she refused to continue taking chlorodehydromethyltestosterone, which resulted in her expulsion from the team by Manfred Ewald.
Career Recognition
Her performance led to significant state recognition, including four consecutive designations as East German Sportspersonality of the Year between 1973 and 1976. She received the Patriotic Order of Merit in Gold and was inducted into the International Swimming Hall of Fame in 1981.
Personal Life
Ender was married to East German Olympic backstroke champion Roland Matthes for four years. She is currently married to Steffen Grummt, a former East German track and field athlete and bobsledder.
