Michel Henri Marie Joseph Wibault (born 5 June 1897, died 23 January 1963) was a French aircraft designer. He was a strong advocate of metal construction, and his airliners were important in the development of French commercial aviation in the 1930s. He is especially known for his invention of vectored thrust for aircraft, which led to the development of the V/STOL Hawker Siddeley Harrier.
Karl Gustav Vollmöller (or Vollmoeller; 7 May 1878 – 18 October 1948) was a German philologist, archaeologist, poet, playwright, screenwriter, and aircraft designer. He is most famous for the elaborate religious spectacle-pantomime The Miracle and the screenplay for the celebrated 1930 film The Blue Angel (Der blaue Engel), which made a star of Marlene Dietrich.
Ludwig Dürr (4 June 1878 in Stuttgart – 1 January 1956 in Friedrichshafen) was a German airship designer.
Walter Blume (10 January 1896 – 27 May 1964) was a German fighter ace of World War I. During World War I, he flew with two fighter squadrons, Jagdstaffel 26 and Jagdstaffel 9 gaining 28 aerial victories and earning the Iron Cross, Royal House Order of Hohenzollern, and the Pour le Merite.Post World War I he became a prominent aircraft designer for both Albatros and Arado, being one of the pioneers of jet propulsion design in airplanes.
Léon Levavasseur (8 January 1863 – 26 February 1922) was a French powerplant engineer, aircraft designer and inventor. His innovations included the V8 engine, direct fuel injection, and liquid engine cooling. Primarily associated with the Antoinette company, he continued to experiment with aircraft design after the company went bankrupt.
Gustave Albin Whitehead (born Gustav Albin Weisskopf; 1 January 1874 – 10 October 1927) was an aviation pioneer who emigrated from Germany to the United States where he designed and built gliders, flying machines, and engines between 1897 and 1915. Controversy surrounds published accounts and Whitehead's own claims that he flew a powered machine successfully several times in 1901 and 1902, predating the first flights by the Wright Brothers in 1903.
Much of Whitehead's reputation rests on a newspaper article which was written as an eyewitness report and describes his powered and sustained flight in Connecticut on 14 August 1901. Over a hundred newspapers in the U.S. and around the world soon repeated information from the article. Several local newspapers also reported on other flight experiments that Whitehead made in 1901 and subsequent years. Whitehead's aircraft designs and experiments were described or mentioned in Scientific American articles and a 1904 book about industrial progress. His public profile faded after about 1915, however, and he died in relative obscurity in 1927.
In the 1930s, a magazine article and book asserted that Whitehead had made powered flights in 1901–02, and the book includes statements from people who said that they had seen various Whitehead flights decades earlier. These published accounts triggered debate among scholars, researchers, and aviation enthusiasts. Mainstream historians have consistently dismissed the Whitehead flight claims, which Orville Wright later described as 'mythical'.
Researchers have studied and attempted to copy Whitehead aircraft. Since the 1980s, enthusiasts in the U.S. and Germany have built and flown replicas of Whitehead's "Number 21" machine using modern engines and modern propellers, and with fundamental changes to the aircraft structure and control systems.
Stanley Hiller Jr. (November 15, 1924 – April 20, 2006), was an American pioneering developer of the helicopter.
Hugo Junkers (3 February 1859 – 3 February 1935) was a German aircraft engineer and aircraft designer who pioneered the design of all-metal airplanes and flying wings. His company, Junkers Flugzeug- und Motorenwerke AG (Junkers Aircraft and Motor Works), was one of the mainstays of the German aircraft industry in the years between World War I and World War II. His multi-engined, all-metal passenger- and freight planes helped establish airlines in Germany and around the world.
In addition to aircraft, Junkers also built both diesel and petrol engines and held various thermodynamic and metallurgical patents. He was also one of the main sponsors of the Bauhaus movement and facilitated the move of the Bauhaus from Weimar to Dessau (where his factory was situated) in 1925.
Amongst the highlights of his career were the Junkers J 1 of 1915, the world's first practical all-metal aircraft, incorporating a cantilever wing design with virtually no external bracing, the Junkers F 13 of 1919 (the world's first all-metal passenger aircraft), the Junkers W 33 (which made the first successful heavier-than-air east-to-west crossing of the Atlantic Ocean), the Junkers G.38 "flying wing", and the Junkers Ju 52, affectionately nicknamed "Tante Ju", one of the most famous airliners of the 1930s.
When the Nazis came into power in 1933, they requested Junkers and his businesses aid in the German re-armament. When Junkers declined, the Nazis placed him under house arrest in 1934 and eventually seized control of his patents and company. He died the following year. Under Nazi control, his company produced some of the most successful German warplanes of the Second World War.
