Abraham Lewin, an educator and a member of the clandestine Oyneg Shabbes (“Joy of the Sabbath”) Archive maintained a diary depicting the wartime events in the Warsaw ghetto.
It is rare in that it covers in real time the Great Deportation of the summer 1942, during which some 265,000 Jews were deported to their deaths in Treblinka, and some 10,000 were murdered within the ghetto. Abraham Lewin survived the Great Deportation and continued documenting the tragic events of the ghetto until his capture by the Nazis.
