Franz Koegler

from Wikipedia, the free encyclopedia

Franz Kögler (born February 24, 1882 in Neustadt an der Orla ; † January 18, 1939 in Freiberg ) was a German civil engineer for geotechnical engineering and one of the founders of soil mechanics in Germany.

Life

He attended secondary school and the three upper classes of the secondary school in Chemnitz and graduated from high school in 1900. Then studied civil engineering at the Technical University of Dresden and received his doctorate.

In November 1905 Kögler became government building supervisor and was assigned to the new building office in Dresden, where he was involved in the renovation of the Niedersedlitz and Reick stations as well as extensive track and road construction and bridges and buildings. In 1910 he was appointed government builder. From 1909 to 1912 he was involved in various state railways, in drafting bridges and high-voltage lines over the Elbe and in calculating structures. Subsequently, he was construction director at the Dresden civil engineering department. In 1914 he joined the German Railway Association as technical director. In addition to his work, Kögler worked from 1905 to 1912 as an assistant to Max Förster at the Technical University, specializing in wood, stone and reinforced concrete bridges as well as civil engineering and iron construction. He completed his habilitation as a private lecturer in bridge construction , structural engineering and strength theory in 1911 and held lectures until 1914; he was also a private lecturer at the Technical University of Berlin from 1914 .

Since October 1918, Kögler was professor of civil engineering (building design theory) and technical mechanics at the Freiberg Mining Academy . From 1924 he set up a soil mechanics laboratory there, which soon enjoyed a great reputation in Germany. Together with his colleague Alfred Scheidig , he published the then well-known textbook Construction Grounds and Buildings in 1938 by Ernst und Sohn. The publications by Kögler and Scheidig on pressure distribution in the subsoil were also known (published in several sequels in structural engineering from 1927 to 1929). From 1928 to 1930 he was rector of the Bergakademie. In the 1930s he developed the first side pressure probe for earth pressure measurement.

In November 1933, Kögler signed the professors' commitment to Adolf Hitler at German universities and colleges .

After his suicide for political and health reasons, the earthworks laboratory was assigned to the TU Dresden in 1939 , where it was merged with the foundation construction laboratory founded in 1936 under the direction of Walter Neuffer and the Terzaghi student Walter Bernatzik became the managing director. One of Kögler's employees in Freiberg was the later professor in Karlsruhe and Minister Hans Leussink .

In 1928 he was a co-founder of Degebo , a forerunner of the DGGT founded after the Second World War .

A prize is named after him at the TU Bergakademie and the Franz-Kögler-Ring in Freiberg. There is a memorial plaque on his Freiberg house.
