This project was conceived by Fred Grubel, director of the Leo Baeck Institute from 1966 until 1994. The Bundesministerium für Bildung und Forschung of the Federal Republic of Germany generously provided financial support for this project, and the Deutsches Zentrum für Luft- und Raumfahrt e.V.'s section on Geisteswissenschaften (humanities) administered the funding. In addition, each author wants to thank the archives that are listed in the bibliography. Further, Marion Kaplan would like to thank Peter Gay for appointing her to the Dorothy and Lewis B. Cullman Center for Scholars and Writers at the New York Public Library and for his encouragement and support. She also thanks Queens College (City University of New York) and New York University for the leaves they provided that made it possible to finish the book, the archivists at the Stiftung "Neue Synagoge Berlin—Centrum Judaicum" who microfilmed materials from the Gesamtarchiv der deutschen Juden for her, the German Women's History Study Group for reading several chapters, and Ruth Kaplan for her scrupulous editing. Robert Liberles thanks the archivists and librarians at the Geheimes Staatsarchiv Preussischer Kulturbesitz in Berlin and the Rare Book Room of the library of the Jewish Theological Seminary, as well as the Department of History at Ben Gurion University and Professor Chava Turniansky of Hebrew University. The authors are also deeply grateful to Michael A. Meyer, Till van Rahden, and the anonymous readers for Oxford University Press for reading and commenting on the whole project and to Elisheva Carlebach and Monika Richarz for reading parts of it. We would also like to thank Frank Mecklenburg, of the Leo Baeck Institute, New York, for his insightful comments on each chapter and for his indispensable, good-natured, and efficient administration of this project.
