The extraordinary true story of Wilhelm Brasse, the Auschwitz prisoner whose photographs exposed the atrocities of the Holocaust and then helped to convict the Nazis at the Nuremberg Trials. 'I looked death in the eyes. I did it fifty thousand times...' Wilhelm Brasse. When Germany invaded Wilhelm Brasse's native Poland in 1939, he was asked to swear allegiance to Hitler and join the Wehrmacht. He refused. He was deported to Auschwitz concentration camp as political prisoner number 3444. A trained portrait photographer, he was ordered by the SS to record the inner workings of the camp. He began by taking identification photographs of the prisoners as they entered the camp, went on to capture the criminal medical experiments of Josef Mengele, and also recorded executions. Between 1940 and 1945, Brasse took around 50,000 photographs of the horror around him. He took them because he had no choice. Eventually, Brasse's conscience wouldn't allow him to hide behind his camera. First he risked his life by joining the camp's Resistance movement, faking documents for prisoners, trying to smuggle images to the outside world to reveal what was happening. Then, when Soviet troops finally advanced on the camp to liberate it, Brasse refused SS orders to destroy his photographs. 'Because the world must know,' he said.
