R. Michael Dov Weissmandel (d. 1957), rabbi and Jewish resistance leader. An Orthodox rabbi, son-in-law and close associate of Rabbi Unger of Nitra, Weissmandel began his public and social activities during the Nazi period when Jews were deported from Slovakia, engaging non-Jewish emissaries to send food, clothing, and money to the deportees temporarily "settled" in the territories of the General Government in Poland. Weissmandel belonged to the core of the underground "Working Group" and was the initiator of the Europa Plan to rescue the remnants of European Jewry. His letters, addressed to the Jewish leadership of the free world "in the style of the Marranos," castigated indifference and begged for action to save the Jewish remnants from extermination. In April 1944, he warned Hungarian Jewry of the impending deportations. A month later, he implored world Jewish leaders to demand that the Allies bomb the murder installations at Auschwitz. In the autumn of 1944, he jumped from a deportation train on its way to Auschwitz. After the war he lived in the United States, where he died. His book of memoirs, Min ha-Mezzar ("From the Depths") was published posthumously in 1960.
