In 1939, Gustav Kleinmann, a Jewish upholster from Vienna, and his sixteen-year-old son Fritz are arrested by the Gestapo and sent to Germany. Imprisoned in the Buchenwald concentration camp, they miraculously survive the Nazis’ murderous brutality. Then Gustav learns he is being sent to Auschwitz—and certain death. For Fritz, letting his father go is unthinkable. Desperate to remain together, Fritz makes an incredible choice: he insists he must go too. To the Nazis, one death camp is the same as another, and so the boy is allowed to follow. Throughout the six years of horror they witness and immeasurable suffering they endure as victims of the camps, one constant keeps them alive: their love and hope for the future. Based on the secret diary that Gustav kept as well as meticulous archival research and interviews with members of the Kleinmann family, including Fritz’s younger brother Kurt, sent to the United States at age eleven to escape the war, The Boy Who Followed His Father into Auschwitz is Gustav and Fritz’s story—an extraordinary account of courage, loyalty, survival, and love that is unforgettable.
