Siegfried and Walter Günter
Dr. Siegfried Günter (8 December 1899 – 20 June 1969) and Walter Günter (8 December 1899 – 21 September 1937) were German twin brothers and pioneering aircraft designers. Walter was responsible for the world's first rocket-powered and turbojet airframes, projects funded by Nazi Germany.〔("The jet race and the Second World War" ), Sterling Michael Pavelec. Greenwood Publishing Group, 2007, p. 5. ISBN 0-275-99355-8, ISBN 978-0-275-99355-9.〕 Siegfried was the father of the "thrust modulation theory",〔 and designs for the Soviet MiG 15 , and MiG 19 .
==Early life==
Siegfried and Walter Günter were born on 8 December 1899 in Thuringia.〔("Aeronautical research in Germany: from Lilienthal until today, Volume 147" ), Ernst-Heinrich Hirschel, Horst Prem, Gero Madelung. Springer, 2004, pp. 66, 69, 379. ISBN 3-540-40645-X, 9783540406457.〕 Avid flight enthusiasts, at 16 they had developed their own propeller theories.〔 Both served in the First World War, where they were captured by the British Army and each became a prisoner of war.
The brothers would be educated in mechancial engineering at the Institute of Technology Hannover, specializing in aircraft design and aerodynamics.〔 It was there that Siegfried designed his first aircraft with fellow students Walter Mertens and Werner Meyer-Cassel, the glider H 6.〔 Their talents were first recognised by Paul Bäumer who was impressed by the performance of the H 6 when he saw it being flown at Wasserkuppe. Bäumer offered the brothers, Mertens, and Meyer-Cassel jobs with his company Bäumer Aero in Berlin. There they began designing motor gliders and then increasingly fast sports planes, including one in which Bäumer himself was killed in a crash in 1928. By 1925 Siegfried had designed first "Buzzing Wind" airplane for the Deutscher Rundflug 1925 competition, which featured the first elliptic design based on Prandtl's 1918 theory.〔
