First published in 1955, with a revised edition appearing five years later, H. G. Adler’s Theresienstadt, 1941-1945 is a foundational work in the field of Holocaust studies. As the first scholarly monograph to describe the particulars of a single camp - the Jewish ghetto in the Czech city of Terezin - it is the single most detailed and comprehensive account of any concentration camp. Adler, a survivor of the camp, divides the book into three sections: a history of the ghetto, a detailed institutional and social analysis of the camp, and an attempt to understand the psychology of the perpetrators and the victims. A collaborative effort between the United States Holocaust Memorial Museum and the Terezin Publishing Project makes this authoritative text on Holocaust history available for the first time in the English language, with a new afterword by the author’s son Jeremy Adler.
