"Gustav Otto (12 January 1883 – 28 February 1926) was a German aircraft and aircraft engine designer and manufacturer.
Otto was born in Cologne to Nicolaus August Otto, the founder of N. A. Otto & Cie. and inventor of the four-stroke internal combustion engine. It is therefore regarded[by whom?] that his interest in engines, specifically aircraft and the manufacture thereof, was something he inherited from his father at an early age." - (en.wikipedia.org 10.04.2024)
