The Mitzvah Project is a combination of theater, history lesson and conversation in which actor and child of survivor, Roger Grunwald, explores one of the most shocking aspects of the Jewish experience during the Second World War. Through the story of Christoph Rosenberg, a German half-Jew, the one-person drama — created with director and co-author Annie McGreevey — reveals the surprising history of tens of thousands of German men known as "mischlinge" — the derogatory term the Nazis used to characterize those descended from one or two Jewish grandparents — who served in Hitler's army. Grunwald's lecture delves deeper into the history that produced these mischling-soldiers — men who were the product of two centuries of German-Jewish assimilation, intermarriage, conversion and the striving of a people committed to calling the German Fatherland their home. After the lecture, Mr. Grunwald leads a discussion with the audience.
