Gerhard Fieseler (1896-1987) started his long aviation career as a German fighter pilot during World War I, in which he was credited with 19 confirmed aerial victories.  In the 1920s he became a celebrated aerobatic display pilot and eventually began designing his own planes for his exhibitions.  In 1930 he purchased a failing glider factory and started Fieseler Flugzeugbau, which produced sport aircraft and then military aircraft for the Luftwaffe.  Fieseler’s two most famous projects were the infamous V-1 unguided missile and the Fi 156 observation plane.  Fieseler ceased to exist as an aircraft manufacturer at the end of World War II, although its plant was used for automobile manufacture.
