Acknowledgments

The Volkswagen Foundation funded the initial research for this book, and it was completed during research leaves from Duke University. Colleagues at Duke were immensely helpful. Stefani Engelstein gave invaluable advice and encouragement. Julianne Werlin provided unceasing intellectual inspiration. Heidi Madden at Perkins Library speedily resolved numerous difficulties. Thomas Pfau, Henry Pickford, and Kata Gellen were models of collegiality and generosity. My work also profited greatly from conversations with several scholars at other universities and research centers, including Gabriel Trop, Eric Downing, Karen Hagemann, and Konrad Jarausch (Chapel Hill); Matthew Birkhold and May Mergenthaler (Ohio); Natalie Binczek and Dorothea Walzer (Bochum); Arnd Wedemeyer (Berlin), Till van Rahden (Montréal), Iwan-Michelangelo d’Aprile and Vinzenz Hoppe (Potsdam); Till Dembeck (Luxembourg); John Noyes (Toronto); Fritz Breithaupt (Indiana); Bill Donahue (Notre Dame); Michael Jennings (Princeton); and Jeffrey Hertel (Hillsdale). For their friendship, I thank Iyman Ahmed, Priscilla Layne, and Chandra Wright.
