The first folder in this collection consists primarily of postcards and letters that Jürgen Sperber wrote to his wife and his parents while he was incarcerated in Camp Crossville, Tennessee. In them, he replies to news that his correspondents have conveyed earlier and reports on his life in camp. Among the subjects he discusses are his desire to see his family, the food in camp, his studies at the camp university, and his hobbies. This folder also includes partial translations of this correspondence, biographical information regarding Sperber, and photographs of Jürgen and Hanna-Lisa Sperber. The second folder houses documents showing Sperber's military service, his participation in Camp Crossville's school, and his discharge from the Luftwaffe. All of the documents in this collection are copies of the originals.
