Otto Kirschmer

from Wikipedia, the free encyclopedia

Otto Kirschmer (born March 24, 1898 in Ingelfingen ; † January 9, 1967 in Darmstadt ) was a German physicist . He worked in the field of fluid mechanics .

Life

His parents were Friederike Kreeb (1866–1923) and Karl Kirschmer (1865–1927), senior teachers in Ulm .

Until he graduated from high school in 1916, he lived in Schöntal , Heidenheim and Ulm. He then volunteered in the mountain artillery in the First World War on the Western Front . After the war, he studied mechanical engineering at the Technical University of Munich from 1919 to 1923 under August Föppl , Moritz Schröter and Jonathan Zenneck .

His partner was Hansi Preisinger (1906–1976), who therefore lost her role as Maria Magdalena at the Oberammergau Passion Play in 1930.

He was a research assistant in the institute of Dieter Thoma (1881–1942). In 1925 he was with the issue studies on the Gefällsverlust to rake the Doctor of Engineering PhD . From 1925 to 1926 Kirschmer worked for the engineering office for turbine, pump and well construction Lawaczeck-Riepel by Franz Lawaczeck (1880-1969, inventor of the Lawaczeck turbine ) and his partner Riepel in Munich as a designer.

In 1926 Kirschmer was next to Oskar von Miller one of the founders of the International Association of Hydraulic Engineering and Research [IAHR] in Basel . Miller pursued the idea of ​​an extensive test facility for hydraulic engineering on the Obernach am Walchensee (near the later Obernach power plant ), which Kirschmer implemented. In 1929, the test facility in Obernach, which was advocated by Ludwig Prandtl , Hubert Engels and Clemens Herschel (1842–1930), began its model tests. The hydraulic research institute achieved international importance under his leadership. From 1930 to 1933 the regulation of the Hwanho was modeled for the Chinese government .

In 1930 Kirschmer was appointed to a professorship at the Technical University of Dresden . For the Reichstag election in July 1932 , he and ten other professors from the TH Dresden called for the election of the NSDAP and entered it on April 1, 1933. In November 1933 he signed the German professors' confession of Adolf Hitler .

In 1934/35 he became rector of the TH. He taught the subjects of hydraulics , flight studies , hydropower plants , pumped storage plants , mechanical engineering and electrical engineering . In addition to the test facility in Obernach, he also managed the river engineering laboratory in Dresden and, after that, project planning work for a new hydrological test facility near Anif . At the beginning of the war in 1939, in addition to his work in Dresden, he worked for the High Command of the Navy in Berlin, Wilhelmshaven and Cuxhaven.

From 1947 to 1949 Kirschmer was scientific director in the Laboratoire d'Hydraulique Saint-Venant in Paris . From 1950, Kirschmer headed the materials testing institute at the MAN Gustavsburg plant and expanded the pipeline and apparatus construction department. From 1953 to 1955 he was a lecturer at the Technical University of Darmstadt and in 1955 he became head of the Institute for Hydromechanics and Hydraulic Engineering.
