Johann doll

Johann "Jean" doll (born April 14, 1882 in Oberhausen ; † December 19, 1941 in Breslau ) was a German engineer .

Life

He attended school in Zwickau . He then worked in numerous domestic and foreign companies from 1896 to 1902. He then began studying chemistry and metallurgy at the Technical University of Berlin-Charlottenburg . In 1906 he passed his diploma examination. He obtained his doctorate in 1909 as Dr.-Ing.

Several study trips followed to visit iron and steel works in Europe and North America. For the Association of German Ironworkers , today's steel institute VDEh , he carried out investigations into the performance of drives and rollers in rolling mills. He also included related questions in his considerations. From 1910 to 1913 he worked at the Technical University in Breslau , where he lived at Auenstrasse 43. At the university he taught metallurgical machinery and rolling mill technology. He was a member of the Corps Montania Breslau .

Then he drew up the plan for the construction of the first special plant for parallel- faced wide flange beams , using his own patent. The project was implemented at Walzwerk AG Peine . From late 1915 to January 1919 he was director of the iron works in Freistadt . Then he worked from 1919 to July 1925 as 1st director in the Witkowitz ironworks in Witkowitz .

He then worked as an expert in the field of iron and steel works in Düsseldorf. He prepared reports for domestic and foreign companies. He advised the Russian government on the reconstruction and expansion of the Russian iron and steel industry. In Düsseldorf he lived at Beethovenstrasse 19.

On June 18, 1934, during a visit to the Magdeburg waterways directorate , Carl Vincent Krogmann found out in a conversation with Wilhelm Keppler that the Reich Minister of Economics had suggested that doll be appointed Reich Commissioner for Raw Materials Management, which then took place in June 1934. Alfred Rosenberg scoffed at him as the new raw materials commissioner without authority . Doll, who came from the practice of the ironworks, viewed the Nazi planning figures as fantasy plans and he considered the Keppler office to be a club of fantasists , as Riedel wrote.

Without competencies, doll could only play an insignificant role in the war armaments of the Nazi regime and was also replaced in 1937. In Berlin he lived at Behrenstrasse 43.
