Assen Jordanoff

Assen "Jerry" Jordanoff (, born Asen Hristov Yordanov, September 2, 1896 - October 19, 1967) was a Bulgarian-American inventor, engineer, and aviator. Jordanoff is considered to be the founder of aeronautical engineering in Bulgaria, as well as a contributor to the development of aviation in the United States.

He occupied a distinct place among pilots of his time, the golden age of airmanship; in America, Jordanoff gained almost legendary status for his many roles as test pilot, airmail and air taxis pilot, stunt pilot, and flying instructor.

He worked as an engineer for a number of companies, including Curtiss-Wright, Boeing, Lockheed, North American, Consolidated, Chance-Vought, Douglas and Piper, where he produced instruction books and manuals for famous airplanes such as the Curtiss P-40 Warhawk, the Lockheed P-38 Lightning, the North American B-25 Mitchell, the Boeing B-17 Flying Fortress, the Consolidated B-24 Liberator, the Boeing B-29 Superfortress, and the Douglas DC-3. Jordanoff was also well known for his numerous educational publications on aeronautics, including his inventions outside the realm of aviation. Provided by Wikipedia
