Hans Gustav roar

to Hans Gustav roar (* 10. February 1895 in Uerdingen, † 10. August 1937 in Koblenz) was a German technical designer and car manufacturer. It created 1926 its own automark, which carried its name, failed however as an entrepreneur. Afterwards it became chief designer at the eagle works AG, where it the well-known eagle play the trump card designed. it changed 1935 as a technical director to Daimler Benz AG. In August 1937 it got sick after a Cabrioletfahrt at a pneumonia with fatal outcome.

early years and first experience with automobiles

the Hans Gustav roar as a son of the owner of a lead rolling mill in Uerdingen in the Rhine country one bore. The family prosperity already made it for it possible 1912 to design with only 17 years, its own airplane. He built it together with its friend and later occupation colleague Joseph Dauben. Already this airplane showed that nearly vision acres talent of its designer. The eve of the First World War, as if wire-strutted double-deckers with row engines as state of the art applied, built roar one with staffs reinforced Eindeckerkonstruktion, which anticipated later, freely carrying construction layouts in the fundamentals. Also the engine assembly was their time ahead: Roar used one from motorcycle cylinders designed 5-Zylinder radial engine . As in the process the following should show up of the war, is better suitable radial engines due to smaller weight and more favorable running properties for airplanes, than other engine variants.

In the First World War served roar first as a flighter pilot, then it changed Sülz for a manufacturer of auto and aircraft engines in Cologne as a civilian to Priamus, -. As a trainee it acquired itself basic knowledge in the construction of engines here. 1918 took part roar also financially with Priamus and placed already shortly thereafter a new radial engine with a weight per horsepower of under 1 kg per HP of pre and with approx. 600 HP of engine performance. That was at that time world point. But because of the shortly thereafter following military defeat one decided to destroy the engine again in order not to let it fall into the hands of the French Besatzer.

With the contract of Versailles winner powers forced German aviation to soil. Therefore concentrated roar on the automotive manufacture. Its first prototype, which it realized 1919 with the Priamus works together with Joseph Dauben, showed already clear characteristics of later constructions: a progressive chassis conception and the lightweight construction characteristics won from the aircraft construction. The prototype, which was meant as inexpensive model for the masses, showed a road-hugging property, which exceeded the quality of luxury automobiles at that time far.

1920 left roar the financially fastened Priamus works, also due to personal differences with the management, toward Berlin. There he built second prototypes, which was equipped with a hydraulic four wheel brake. That was in the building of road cars, the brake made however problems revolutionary and roars recognized also that motorizing did not meet the slowly growing requirements of the market.

roar to car AG

at the end of of 1923 built Hans Gustav roar to third prototypes, a car with 6-Zylindermotor, full rocker axles and a very low emphasis. It tried to sell this vehicle to the established automobile industry as license model. Despite large enthusiasm many entrepreneurs the venture was too large. Thus roar, the necessary moneys themselves decided to constituted and the cars under own name to marked out. 1924 became and. A. with funds of the entrepreneur family Stinnes roar to car AG in upper RAM city with Darmstadt based. For this one took over the manufacturing plants of the earlier Falcon Automobilwerke. The manufacturing started 1927 with roars to 8, a model of the upper middle class, with 8-Zylindermotor (40 HP), low bed platform frameworks and, owing to full rocker axles, outstanding handling characteristics. Nevertheless found the first genuine roar only scarcely 100 buyers, debt was probably the engine, which was neither particularly strong, still very stable.

As if roar 1928 in the international motor show in Berlin participated, it the somewhat unreliable engine had optimized, it got more capacity and an increase in output on 50 HP. The new vehicle model was called now roars to 8 type R and became the first commercial success of the young automobile producer. From 1928 to 1930 approximately 1,000 vehicles sold themselves.

But 1929 were seized also the roaring car AG by the downward vortex of the world economic crisis. The enterprise increased to 800 coworkers lost his principal shareholder Dr. Hugo Greffenius and did not find new backers. At the end of of 1930 was opened settlement proceedings, the share value of the enterprise sank from 3,5 to 1,4 millions Realm Mark. Roar and Dauben had roar to 8 RA briefly before with increased engine performance and to unite technical improvements brought on the market. But the bankruptcy was not to be stopped no more. At the beginning of of 1931 stopped production for the time being. Those roar to car AG with agreement of the creditors by the Swiss roaring general representative Joos Andreas Heintz one took over. Under the name new one roar to AG in April 1931 production again one took up, the straight 36-jährige Hans Gustav roar had to be enterprises however to leave.

chief designer with eagle play the trump card

already in May 1931 found roar and Dauben a new operating field at the likewise crisis-vibrated eagle works AG in Frankfurt/Main. As a chief designer roars 1932 placed the eagle already plays the trump card on the wheels. Typical roaring characteristics, like Tiefbettrahmen and full rocker axles, made play the trump card, after its presentation in March 1932 on the automobile salon in Geneva, to a large commercial success for eagles. The small 1,5-Liter-Fronttriebler reüssierte also with long-distance competitions and mountain valuations - front wheel drive, low emphasis and small weight made it possible.

Until 1934 pushed roar untiringly further models after: The eagles favorite and standard 6 already existing were revised according to its principles. The new play the trump card junior should even the most successful car become, which roar ever would build: Scarcely 103,000 copies left the workshops at the Main to 1941.

National Socialist realm motorway the project changed the work statements of the German automobile technical designers. Stability and streamline became the key words of the time. Roar began with pre-working for a streamline model, but of eagle the 1937 presented first German streamline series car, which eagles of 2.5 litres „motorway “, at the end of Karl Jentschke for eagles one designed. Roar had itself to 1935 with his employer überworfen, because it wanted to the license releases to be taken part, which for foreign production play the trump card junior from France and Belgium flowed.

technical director at Daimler Benz

Hans Gustav roar and to Joseph Dauben found accomodation, again once as a team, at Daimler Benz AG in Sindelfingen . Roar under unfavorable circumstances over the supervisory board by Daimler Benz into the position of the technical director one heaved. His predecessor Dr. Hans Nibel had deceased at the end of of 1934. Replacement was urgently looked for, but the Daimler Benz executive committee under Dr. Kissel did not want roars necessarily to have, because it was no more present-presenting German despite large achievements. Its marriage with a Französin made it suspicious for the Nazis. In addition it came that the wife placed herself publicly against the regime. Therefore one paid attention Dauben during the contract design with roars and precisely to the fact that the new coworkers did not receive views of military projects.

Made itself additional roar unpopularly with „the old “Daimler Benz technical designers. They were pleased few that „the new ones were set for them “simply before the nose. Beside Dauben finally still some further colleagues of eagle came along. Until 1937 the team fell itself over roars intensively on the development of new vehicles with front wheel drive and 4, 6 - and/or. 8-Zylindermotoren. Some test vehicles were already finished placed. Individually hung up wheels and even basic bodies belonged likewise to the special characteristics of these prototypes. The executive committee decided however already 1936 against a series production that practically manufactures models. A hard impact for roar, which had obviously failed because of in-house resentment opposite it, but probably because of its unsatisfactory adaptability. Its further way at Daimler Benz was blocked thereby and in its deduction was vouchers for the fact that it wanted to leave this enterprise anyway soon. But in addition it did not come any longer: To Hans Gustav roar died very surprisingly to 10. August 1937 with only 42 years. It had tightened itself after a Cabrioletfahrt to the only castle ring a deadly pneumonia. Immediately after its death its documents and plans were destroyed by its opponents at Daimler Benz.

to appreciation

Hans Gustav roar was one of the most progressive German automobile technical designers. Its failure did not mean that its ideas would have been wrong. Completely on the contrary: The chassis improvements, individually hung up wheels pushed by it, the lightweight construction with low emphasis and the front wheel drive proved later their superiority.

Roar failed actually because of the problems his time and probably at his Naturell. As car manufacturers forced it the world economic crisis into the knees. Its extremely successful time with eagle ended with business differences. And at Daimler Benz it was not very welcome as newcomers with own ideas. In addition its political adjustment will lacking, from today's viewpoint honorable, came at that time a devastating character error. In his technical ideas and developments is roar never failed. After his death adversaries and the Nazi guidance ensured for the fact that a veil of forgetting fell over its names. Noticed in automobile history roar probably therefore as hardly well-known edge figure.
