Otto Kissenberth (26 February 1893 – 2 August 1919) was a German flying ace of World War I credited with 20 aerial victories.

Upon recovery, he joined another Bavarian unit, Flieger-Abteilung (Flier Detachment) 9b, on 8 July 1915, which was stationed at Toblach in the Dolomite Alps.

The unit served in Italy, including a daring bombing raid on Cortina on 31 July 1915, as well as on the Vosges front.

[1] In 1916, FA 9b morphed into Kampfeinsitzerkommando (Combat Single-Seater Command) KEK Einsisheim, as the German Army struggled to find a tactical formation for its fighters.

An Anglo-French bombing raid of some three French squadrons, 26 aircraft from the Royal Naval Air Service, and a contingent of four from the Lafayette Escadrille attacked the Mauser Rifle Works at Oberndorf am Neckar.

He thus became one of the few flying aces — along with pioneering fighter pilot, Leutnant Kurt Wintgens — to wear spectacles in air combat.
