Ewa Kłobukowska

Ewa Janina Kłobukowska is a Polish former sprinter. She competed at the 1964 Olympics in the 4×100 m relay and 100 m sprint and won a gold and a bronze medal, respectively. She also won two gold and one silver medal at the 1966 European Championships. Kłobukowska set three world records, one in the 100 m and two in the 4×100 m relay. They were annulled by the International Association of Athletics Federations (IAAF) after a gender identification test in 1967 wrongly labeled her as not female. The test procedures were later found to be inadequate.
