At this point, I would like to once again thank all those who provided me with assistance from 1999–2004 as I was doing research for this book in archives and libraries, in particular, Bernadine Pejovic (Völkerbundarchiv - League of Nations Archive - Geneva), Gregor Pickro (Bundesarchiv - Federal Archive - Koblenz), Anne C. Kjeling (Nobelarchiv - Nobel Archive - Oslo) and Peter Grupp (Politisches Archiv des Auswärtigen Amtes - The Political Archive of the Foreign Office).
I especially want to thank my dissertation advisor, Karl Holl, and Dieter Senghaas, who facilitated contact with the Berghof Foundation without whose generous subsidies I would not have been able to travel to many important archives.
Two people are primarily responsible for the publication of this book: Peter van den Dungen, who enthusiastically and repeatedly urged me to look for a publisher and who ultimately was personally involved in the search; and Anne Rüffer, who accepted the manuscript and whose great care and encouragement ensured that the dissertation was appropriately revised into a book-length biography.
