My father was a spy during the Cold War. Bilingual in German and English, he worked for the U.S. Air Force and sent agents into East Germany and elsewhere behind the Iron Curtain in the early 1960's. The Need-to-Know, a photo book, is my exploration of the meager details that emerged from brief and cryptic conversations with my father and my curiosity about Cold War espionage and its impact upon my family at the time. The book was published by Blow Up Press of Warsaw, Poland in October, 2023.
