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.
Biography
Junkers was born in Rheydt in the Prussian Rhine Province, the son of a wealthy industrialist. After taking his Abitur exams in 1878, he attended the Technische Hochschulen in Charlottenburg (now Technische Universität Berlin) and Aachen (now RWTH Aachen), where he completed his engineering studies in 1883.
At first, he returned to Rheydt to work in his father's company, but soon attended further lectures on electromagnetism and thermodynamics held by Adolf Slaby in Charlottenburg. Slaby placed him with the Continental-Gasgesellschaft in Dessau, where he worked on the development of the first opposed-piston engine. To measure heating value, Junkers patented a calorimeter and founded a manufacturing company in 1892. Junkers personally introduced the calorimeter at the 1893 World's Columbian Exposition in Chicago, where it was awarded a gold medal. The next year, he patented a gas-fired bath boiler, which he refined as a tankless heater. In 1895, he founded Junkers & Co. to utilize his inventions.
From 1897, he was offered a professorship of mechanical engineering at Aachen, where he lectured until 1912. Working as an engineer at the same time, Junkers taking substantial gains of Junkers & Co. devised, patented, and exploited calorimeters, domestic appliances (gas stoves), pressure regulators, gas oil engines, fan heaters, and other inventions.

Legacy
Hugo Junkers is mainly known in connection with aircraft bearing his name. These include some he reluctantly developed for the German Empire during World War I, later in minor association with Anthony Fokker, as well as civil aircraft designs during the "interwar period" produced by Junkers Flugzeugwerke (Junkers Aircraft Works).
The earliest all-metal post-World War I aircraft designs of both Andrei Tupolev — with his Tupolev ANT-2 two-passenger small aircraft of 1924 — and William Bushnell Stout's initial all-metal design, the Stout ST twin-engine torpedo bomber of 1922, were both based directly on the pioneering work of Junkers, with each engineer (one Soviet, one American) separately developing examples of aircraft like Tupolev's enormous, 63 meter wingspan, eight-engined Maksim Gorki — the largest aircraft built anywhere in the world in the early 1930s — and Stout's popular Ford Trimotor airliner.
In 1976, Junkers was inducted into the International Air & Space Hall of Fame.[4]
Junkers was featured in the 2013 semi-fictional movie The Wind Rises by Japanese director Hayao Miyazaki.[5]

- Junkers factory designations for their aircraft in the WWI period used Arabic numerals, as in the Junkers J 1 Blechesel, while the later armored J.I all-metal sesquiplane - with factory designation J 4 - was so designated because the Kaiser's Inspektorat der Fliegertruppen army aviation inspectorate used the letter "J", followed by a Roman numeral only, to designate all armored, infantry co-operation and ground-attack aircraft, which were also designed by the Albatros and AEG firms in WWI.^
