Fritz Otto Bernert was a German fighter ace of the First World War, notable for shooting down five enemy airplanes in 20 minutes. Invalided from infantry service after suffering four wounds, he turned to aviation service. Despite wearing pince-nez and having the use of only one arm, he became a pilot. After his first victory with Kampfeinsitzerkommando Vaux, he switched to Jagdstaffel 4, scoring six more victories during 1916. In 1917, he claimed an additional 20 victories between March and May 1917.
