Karl Kollmann (engineer)

Karl Kollmann (born November 18, 1902 in Schweinfurt , † June 26, 1988 in Karlsruhe ) was a German engineer and university professor.

Life

His parents were the Ministerialrat Dr. med. hc Theodor Kollmann and Elisabeth, b. Kuffer. His father had planned, among other things, the local justice building and from 1903 the tax office in Munich and the women's clinic on Maistraße .

After attending Munich's Maximilian Gymnasium, Karl Kollmann studied mechanical engineering at the Technical University of Munich from 1921, where he passed the diploma examination for mechanical engineering and electrical engineering in 1925. For two years he worked at AEG in Berlin under the power plant builder Friedrich Münzinger in the department for heat technology and was then assistant to Wilhelm Nusselt for four years at the TH Munich . In 1931 he received his doctorate in engineering.

In 1932 he married Johanna Rietdorf, with whom he had five children.

At August Borsig GmbH in Berlin-Tegel, he initially worked in steam boiler development (thermal calculation and machine design). In 1933 he joined the design department for aircraft engines at Daimler-Benz, initially as Albert Friedrich's deputy . He was appointed chief engineer and then head of the design office and granted power of attorney.

After the end of the war he worked for the French company Turbomeca in the field of jet engines and was managing director for Adolf Schnürle for three years and was involved in the development of two-stroke diesel engines for trucks. From 1949 he was head of the design department for automatic transmissions at Daimler-Benz in Untertürkheim.

In 1951 he was appointed to the chair for machine design and automotive engineering at the Technical University of Karlsruhe. In 1983 he was awarded the Grashof Memorial Medal from the Association of German Engineers .
