Karl Federhofer
Karl Federhofer (born July 5, 1885 in Knittelfeld , Styria , † November 6, 1960 in Graz ) was an Austrian civil engineer.
Federhofer was the son of a train driver and attended school in Linz and Graz. From 1903 to 1908 he studied civil engineering at the TH Graz , where he received his doctorate in 1909 under Ferdinand Wittenbauer . He was briefly in the construction service of the Austrian State Railways and then in the State Construction Service of Styria. During the First World War, he supervised the construction of the bridge there. In 1913 he completed his habilitation at the Montanistische Hochschule Leoben, was from 1920 full professor for mechanics at the German Technical University Brno and in 1923 full professor for general mechanics, hydrodynamics and aeromechanics at the TH Graz. In 1925/26 he was dean of the Faculty of Civil Engineering and in 1928/29 rector . In 1938/39 he held a leading position in Graz in the National Socialist German Lecturer Association and in 1939/40 he was an honorary member of the academic flying group.
In 1931 he was appointed to the TH Munich, 1939 to the TH Vienna and 1941 to Breslau, which he refused. From 1934 he represented Austria in the International Committee for Technical Mechanics.
From 1946 he was co-editor of the Austrian engineering archive.
Federhofer expanded the graphic treatment of the dynamics of his teacher Wittenbauer further.
In 1935 he became a corresponding and in 1939 a full member of the Austrian Academy of Sciences and was honorary doctor of the TH Vienna (1952) and the TH Darmstadt (1955). In 1959 he received the Austrian Decoration of Honor for Science and Art .
He is the father of the musicologist Hellmut Federhofer and the uncle of the civil engineer Friedrich Reinitzhuber .
