considers how the US Government commissioned the US Signal Corps and other filmmakers to document the horrors of the concentration camps during the April-May 1945 liberation. The evidence of the Nazis' genocidal actions amassed in these films, some of them made by Hollywood luminaries such as John Ford and Billy Wilder, would go on to have a major impact at the Nuremberg Trials; they helped to indict Nazi officials as the judges witnessed scenes of torture, human experimentation and extermination of Jews and non-Jews in the gas chambers and crematoria. These films, some produced by the Soviets, were integral to the war crime trials that followed the Holocaust and the Second World War, and this book provides a thorough, close analysis of the footage in these films and their historical significance.Using research carried out at the Museum of Jewish Heritage, the US National Archives and the film collection at the National Center for Jewish Film at Brandeis University, this book explores the rationale for filming the atrocities and their use in the subsequent trials of Nazi officials in greater detail than anything previously published. Including an extensive bibliography and filmography, is an important text for scholars and students of the Holocaust and its aftermath.
