Rokhl Auerbach was a journalist, literary critic, and one of only three surviving members of the Oyneg Shabes, historian Emanuel Ringelblum' s top-secret archive of the Warsaw Ghetto. Upon immigrating to Israel in 1950 she founded the witness testimony division at Yad Vashem and played a foundational role in the development of Holocaust memory. Warsaw Testament, a memoir based on her wartime writings both in the ghetto and on the Aryan side of the occupied city, provides an unmatched portrait of the last days of Warsaw' s Yiddish literary and cultural community— and of Auerbach' s own struggle to survive.
