J.Herris German Aircraft of Minor Manufacturers in WW1. Vol II (A Centennial Perspective on Great War Airplanes 50)

Karl Krieger

   Together with his brother Oskar, he built a torpedo aircraft in 1914, which he wanted to patent. Alarmed by this writing, the Reichsmarineamt confiscated the triplane, but Krieger took legal action against it and won. The Reichsmarineamt then had to pay 50,000 Marks in damages, which, however, failed to materialise due to the war that had broken out in the meantime.
