Leutnant Friedrich Friedrichs was a World War I fighter ace credited with 21 confirmed victories. Undaunted by an early invaliding by infantry combat during early World War I, Friedrichs switched to aviation. After serving reconnaissance duty, he moved to being a fighter pilot with Jagdstaffel 10. He shot down 11 enemy observation balloons, making him a top balloon buster; he also shot down 10 enemy airplanes. He was killed in action on 15 July 1918 when his Fokker D.VII burst into flames in midair.
