Louis Hagen (1916–2000), born into a Jewish banking family, was sent to Schloss Lichtenburg concentration camp for writing an anti-Nazi joke on a postcard to his sister. A high-ranking Nazi judge and friend of the family got him out and he escaped to England. He eventually became a glider pilot, fighting for the British at Arnhem. He is the author of several books, including Arnhem Lift based on that experience. He went on to be a successful journalist and film producer.
