Members of the Frank family generously provided me with many of the materials that would become the lifeblood of this book. Nicholas Frank was the first to introduce me to his family history. Patrick and Michael Frank then entrusted me with the family’s collection of journals, letters, memoirs, interviews, and photos from the war years and earlier. They also put me in touch with their cousin Barbara Weldon, who graciously shared with me her own trove of historical documents. I am indebted to Patrick and Michael for reading and commenting on an early draft of this book. Patrick in particular spent many hours researching and vigorously cri- tiquing some of my assertions; the book has benefited enormously from his input.
