This book is a study of altruism during the Holocaust. The author and her staff interviewed more than 300 rescuers in North America, Israel and various European nations and confirmed each rescuer's recollections by interviewing the Jews they saved or checking it against archival material. Their goal in this was to find the motivation behind alturism. Why did these people defy authority and put themselves at risk to act humanely? It is also hoped that by recording these stories and studying them, these acts of compassion will never be forgotten and they will be repeated, again, and again.
