Szymon Datner

In 1928 Datner settled in Białystok.[2] Before the outbreak of World War II, he worked as a physical-education teacher at a Jewish secondary school in Białystok. He lived in that city with his wife and two daughters through the Soviet occupation of eastern Poland. After the German attack on the Soviet Union, he was forced with his family into the Białystok Ghetto. On 24 May 1943 he helped smuggle several persons out of the Ghetto. However, his wife and daughters did not survive its liquidation.

After the war, Datner served for two years as head of the Białystok branch of the Central Committee of Jews in Poland (CŻKH). "A survivor himself, he deposited his own testimony at the Jewish Historical Commission in Białystok on 28 September 1946."[3]

The same year, the CŻKH published his Walka i zagłada Białostockiego Ghetta (The Struggle and Destruction of the Białystok Ghetto).[2] In the late 1940s Datner moved to Warsaw. He became a prominent specialist on World War II crimes and the Holocaust.[3] Of Jewish extraction, he was dismissed from his post during the 1968 Polish political crisis but was rehabilitated soon after.

In 1969–70 he presided over Warsaw's Jewish Historical Institute, and he was one of the historians at the Main Commission to Investigate Hitlerite Crimes.[4] According to Bernd Wegner, Datner drew up the most comprehensive documentation of Nazi Germany's war crimes and atrocities in eastern Poland.[5] In 1966 he published an article on "The Extermination of the Jewish Population in the District of Bialystok", which also mentions the Jedwabne pogrom; however, due to censorship in communist Poland, he could not openly write on anti-Jewish pogroms.[3]According to Datner, German units operating in Bialystok District while themselves engaged in exterminating Jews, also acted as instigators, compelling the cooperation of local people[3]

Datner died in 1989 in Warsaw and is interred at the Okopowa Street Jewish Cemetery.
