Аннотация:During World War II, over one and a half million Jews were murdered in the three extermination camps of Operation Reinhard: Belzec, Sobibor and Treblinka. Indeed, these death factories figure prominently in the history of the Holocaust. Yet while there are an apparently endless number of publications available on Auschwitz, researchers have largely neglected the three extermination camps of Operation Reinhard. Until recently, the standard work by Yitzhak Arad, more than twenty-five years old, was the only high-quality monograph on the subject. That changed in 2013 with the release of a study by the recently deceased Polish historian Robert Kuwalek on the Belzec extermination camp and, that very same year, the publication of Sara Berger’s work, which is based on a dissertation submitted to the University of Bochum. Berger’s study focuses on the perpetrators in the three camps. She thus joins the ranks of a new generation of researchers seeking to shed light on the perpetrators of National Socialism ( neue Täterforschung ) and expands on this approach with a convincing use of the analytic tools of social science network research. This results in a collective biography of the 121 men whom Berger identifies as the core of the Operation Reinhard network. Berger looks beyond the actions of the perpetrators in the three camps and conducts extensive research into what these men did before and after the war. Furthermore, she examines the history of the camps, producing research that often goes beyond the level previously achieved by Arad.
