This book has been a long time in the making and has accompanied me through multiple personal and professional changes. Both I and the political and intellectual milieu I inhabit were quite different when I first became intrigued with the German sex reform movement, and I have incurred innumerable debts in the process of trying to figure out how to tell a story in the 1990s that I began to think about in the 1970s. Luckily, I was not alone in this venture, and I am happy to acknowledge—inevitably inadequately—the support that kept me going.
To start with the crucial institutional level, I am grateful for research and travel funding and leave time—never enough it seems, but indispensable— to the American Council of Learned Societies, the National Endowment for the Humanities summer fellowship program, the German-American Academic Exchange Service, and Columbia University's Councils for Research in the Humanities and Social Sciences and Junior Faculty Development Leave. A large crew of archivists, librarians, colleagues, and interview partners facilitated my access to source materials, some of them—like the Weimar sex magazines that Gudrun Schwarz and I excavated from the basement of the West BerlinStaatsbibliothek in the late 1970s—buried and forgotten since 1933. I am particularly grateful to Dr. Jürgen Wetzel of the Landesarchiv Berlin, Ilona Kalb of the Humboldt University archive, Esther Katz of the Margaret Sanger Papers Project, Sabine Schleiermacher of Hanover University, and the by now world famous Herr Lange, formerly of the Institute for the History of Marxism Leninism in East Berlin and now a part of the Bundesarchiv. Veterans of the sex reform movement and their children and grandchildren gave generously of their time and knowledge, often proud to tell their stories, sometimes (especially at the earlier stages) amazed that anyone was still interested.
