In 1928 Datner settled inBiałystok.[3] Before the outbreak ofWorld War II, he worked as aphysical-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 theSoviet Union, he was forced with his family into theBiałystok Ghetto. On 24 May 1943 he helped smuggle several persons out of the Ghetto. However, his wife and daughters did not survive its liquidation.[citation needed]
After the war, Datner served for two years as head of the Białystok branch of theCentral 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."[4]
The same year, theCŻKH published hisWalka i zagłada Białostockiego Ghetta (The Struggle and Destruction of the Białystok Ghetto).[3] In the late 1940s Datner moved toWarsaw. He became a prominent specialist on World War II crimes andthe Holocaust.[4] OfJewish extraction, he was dismissed from his post during the1968 Polish political crisis but was rehabilitated soon after.
