From 1940 to 1943, the Warsaw ghetto was cut off from the outside world, besieged by hunger, cold, sickness and terror.
But at the heart of this hell on earth, a group of men and women gave themselves the Yiddish name of Oyneg Shabbes ("joy of the Sabbath") and joined the historian
Emmanuel Ringelblum in the patient and perilous task of studying and collecting information on the fate of the Jewish community within the ghetto and more generally in the
Nazi-occupied territories. Carefully concealed and later partially retrieved in the ruins of the ghetto after the war, this unique testimony has been passed down to posterity
under the name of «The Ringelblum Archives".
