The Polish institute is named after Jewish historian Emanuel Ringelblum, who managed to bury all of his notes in the ground before being murdered by the Nazis.
Ringelblum collected diaries and documents that formed a real archive documenting life in the Warsaw Ghetto. The papers, which were discovered after the war, provide a horrifying account of what took place in the ghetto.
The Jewish Historical Institute is considered one of the most important of its kind in the world. The cooperation agreement will enable the Jerusalem Holocaust Museum to obtain and distribute new information on the fate of Warsaw Jews.
