This book could not have been written without the generous assistance of many people and institutions. It is a pleasure to be able to thank them here. The research for this book was supported by major grants from the German Academic Exchange Service (DAAD), the Mabelle McLeod Lewis Memorial Fund, and the Harry Frank Guggenheim Foundation. In addition, I was fortunate to spend a year as Geballe Dissertation Fellow at the Stanford Humanities Center and a later year as a James Bryant Conant Post-Doctoral Fellow at the Center for European Studies at Harvard University. The University of Maryland General Research Board and the National Endowment for the Humanities provided summer stipends at key points in the project.
The librarians of the Staatsbibliothek Preussischer Kulturbesitz in Berlin, Green Library at Stanford University, Widener Library at Harvard, the International Legal Studies Reading Room of the Harvard Law School Library, the National Library of Medicine in Bethesda, and McKeldin Library at the University of Maryland facilitated access to many of the sources on which this study is based. I am particularly indebted to the Interlibrary Loan offices at Stanford, Harvard, and the University of Maryland, who worked hard to locate rare materials. The archivists of the Bundesarchiv, Abteilung Potsdam, the Bayerisches Hauptstaatsarchiv in Munich, and the National Archives in College Park, Maryland, allowed me to consult crucial archival materials.
I have benefited greatly from the advice and encouragement of many friends and colleagues.
