Ernst Udet
AGO was founded in 1911 in Munich as "Flugmaschinenwerke Gustav Otto" by Gustav Otto and a Dr Alberti. Gustav, the son of Nicolaus Otto – inventor of the four-stroke engine, was a pioneer aviator (pilot's licence No. 34) and engine-builder. As was usual in those days, a flying school was attached to the business – one of its later students was Ernst Udet.
