   Dates unknown

Alexander "Sasha" Aronovich Pechersky (Russian: Алекса́ндр Аро́нович Пече́рский; 22 February 1909 – 19 January 1990), also known as Oleksandr Aronovych Pecherskyi (Ukrainian: Олександр Аронович Печерський), was a Jewish-Soviet officer. He is one of the organizers, and the leader, of the most successful uprising and mass-escape of Jews from a Nazi extermination camp during World War II, which occurred at the Sobibor extermination camp on 14 October 1943. In 1948, Pechersky was arrested by the Soviet authorities along with his brother during the countrywide Rootless cosmopolitan campaign against Jews suspected of pro-Western leanings but released later due in part to mounting international pressure. Pechersky was prevented by the Soviet government from leaving the country to testify in international trials related to Sobibor, including the Eichmann Trial in Israel; foreign investigators were only allowed to collect his testimony under KGB supervision. The last time he was refused permission to exit the country and testify was in 1987, for a trial in Poland.
