Raymond-Raoul Lambert's Diary has been among the most important untranslated records of the experience of French Jews in the Holocaust. Lambert, a leader of the Union of French Jews (UGIF), was, in the words of the historian Michael Marrus, "arguably the most important Jewish official in contact with the Vichy government and the Germans." Lambert's Diary survived the war and was published in France in 1985. It reveals Lambert's efforts to save the Jews in France, particularly the children.
