Stanislawa Walasiewicz

Polish track and field athlete, who became a women's Olympic champion in the 100 metres. It was later learned that Walasiewicz had male genitalia and was intersex.

Walsh was killed during an armed robbery in Cleveland, Ohio, on 4 December 1980. An autopsy showed that she possessed male genitalia, although some sources suggest she also displayed some female characteristics. Detailed investigation has also revealed that she had both 45X0 and 46XY chromosomes.

The controversy of her biological sex remains unresolved, and the situation is further complicated by the fact that many earlier documents, including her birth record, state that she was female. There was also some controversy as to whether all her records and achievements should be erased.
