Hugo Junkers - Inventor and Scientist, Constructor and Aircraft Pioneer Asking for famous personalities on the streets of Dessau whose work has made the town well known, most of the involved persons would answer “Hugo Junkers”. There has been written and spoken a lot about him up to now and his merits are well known. On May the 24th 1928 the chairman of the Dessau district council requested in a non-public extraordinary meeting:
„... to award Professor Dr. Ing. h.c. Hugo Junkers, on the occasion of the 1000th aircraft

built by the Junker-factories in recognition of excellent accomplishments he has acquired for the German aviation, to award him the “Freedom of the City of Dessau” according to § 58.3 of the municipal law and to name the street Köthener Straße leading along the factories “Junkersstraße”.
(Anhaltischer Anzeiger - May 25th 1928) In 1859 Hugo Junkers was born in Rheydt, situated on the left bank of the River Rhine as the son of a weaving mill owner. He was an engineer and constructor, a savant and entrepreneur.
He took his final examination at the upper vocational school in Barmen. After his studies at the universities in Berlin-Charlottenburg, Karlsruhe and Aachen he worked as a constructor in engine construction factories of the Rhineland.

The mechanical engineer Hugo Junkers started his career at the Deutsche Continental-Gasgesellschaft. In 1892 he even founded his first office as “Hugo Junkers, Civilingenieur”. His patent for a new type of high-pressure gas engine was the first of 380 patented inventions which were registered in the course of his life. He successfully researched on several techniques. He designed gas oil- and heavy oil engines, heat exchangers, metal houses, halls and highrise buildings and of course all-metal aircraft.

Hugo Junkers is undoubtedly one of the most famous German inventors. In 1895 he founded his first factory, the „Junkers & Co., Fabrik für Gasapparate” (Gas Appliance Factory).
Apart from having a professor’s chair at the Aachen University of Technology, which he obtained in 1897, he devoted himself to his further research work and in 1902 he founded a research laboratory for investigation of basic thermal problems in engine operation. After he had got in contact with aircraft construction in 1910 he aquired the patent for a “All-Wing-Plane”.
In 1915 his first all-metal aircraft “J 1“ with self-supporting wings was developed. In 1919 he build the single-engined airliner “F 13“ in the newly founded factory for aircraft the “Junkers-Flugzeugwerke AG Dessau“.

After World War I Junkers turned to the construction of multi-engine airlcraft, which belonged to the safest and most used in the world. He also was involved in the foundation of airline companies.
In October 1933 the National Socialists forced Junkers to transfer most of the stocks of his companies to the German Reich and give up his leadership of the Junkers Company.

On the 3rd of February (his birthday) 1935 Hugo Junkers, the versatile scientist and successful entrepreneur, died at the age of 76. His basic research work was always geared to direct application. It was not only the theoretical realization which was important for him but above all the patented result for the fabrication as a unit of shape and function.

East-West Trans-Atlantic Crossing
In 1927 Charles Lindberg, an American, overflew the Atlantic in his Ryan NYP “Spirit of St. Louis” in west-east direction. Inspired with the idea of crossing the Atlantic in the opposed direction, from east to west, the initiator of the BREMEN flight baron von Hünefeld set everything in motion in order to put his thoughts into practise...

Exhibition Documents - The history of the museums beginning
In the time of social upheaval, the thought arose to erect a museum on the area of the former Junkers’ aircraft factory. In 1992, involved Dessau’ citizen and former factory members founded an association with the aim to support the erection of a Technikmuseum. The “promoting association” begun to collect exhibits and acquired a part of former area of Junkers with an empty being factory hall from the 50s....

Junkers - Pioneer of Aviation
Hugo Junkers is the father of civil commercial aviation. His first all metal aircraft F 13 set standards and in its typical corrugated metal design, it dominated an era of aircraft history of more than two decades. In the twenties and thirties of the 19th century the use of Duralumin and an own development of aero-engines made Germany a leading nation in aviation by his aircraft developments....

Heat technology and gas appliances
In 1887, Hugo Junkers graduated from the Technical University of Berlin-Charlottenburg where he studied electronic engineering and heat technology at Professor Slaby. The theoretical knowledge he gained there played an important role in his future professional career. Recommended by his Berlin professor, Hugo Junkers joint the Deutsche Continental Gasgesellschaft in Dessau, where Wilhelm Oechelhaueuser (senior) was the technical director. He moved to Dessau where began the most fruitful period of his creative life. 114 patents were granted only in the field of gas and heat technology....

Engine construction
Junkers gained his theoretical knowledge in the universities of Karlsruhe, Aachen and Berlin-Charlottenburg. He studied traditional machine construction as well as electronic engineering and heat technology. This knowledge helped him in his work at Deutsche Continental Gasgesell-schaft in Dessau. In 1892, he used the principle of opposed pistons in the gas engine for the first time. This was followed by decades of development work in the field of engine technology....

Ju52-Report The history of the legendary plane
In 1909 Hugo Junkers turned to a new area of activity: aerodynamics and powered flights. Together with Prof. H. Reissner, he tried to establish scientific foundations in aerodynamics. His knowledge in fluid mechanics, material testing and metal construction helped him with his work.
In 1915 the J 1, the so called “Tin Donkey”, took off an reached a climbing speed of 105mph....
