A NUMBER OF PEOPLE have been very helpful to me. Some belong to the Tocqueville community of scholars, others are personal friends or colleagues. I especially want to thank Richard Arena, Patrik Aspers, Roger Boesche, Dan Cook, Michael Drolet, Niclás Eilbaum, Laura Ford, Robert Ganett, Arthur Goldhammer, Andreas Hess, Claus Offe, Jennifer Platt, Scott Sandage, Charlie Smith, Wendelin Reich, Jeff Weintraub, Ningxi Zhang, and Olivier Zunz.
A special thanks goes to Françoise Mélonio and James Schleifer for sharing their great knowledge about Tocqueville, and to Philippe Steiner for tutoring me in the history of French economic thought. For helping me consult the Archives d'Alexis de Tocqueville, which are housed at the Archives départementales de la Manche, I thank Jean-Guillaume de Tocqueville d'Hérouville and its director, Gilles Désiré Dit Grosset. Susan LoBello kindly corrected my translations of Tocqueville quotes; and Marty White did wonders with the illustrations. I am grateful to Cornell University Library and Beinecke Rare Book and Manuscript Library. Many people at Princeton University Press helped me greatly with this book. Special thanks go to Tim Sullivan, who was my editor, and William Chang, his assistant. Deborah Tegarden has been an excellent production editor and Jenn Backer an excellent copyeditor.
Mabel Berezin has been my muse.
