Wilhelm Friedrich Kohlrausch (born May 14, 1855 in Marburg , † April 16, 1936 in Hanover ) was a German physicist and, as a university lecturer in electrical engineering, Rector of the Technical University of Hanover from 1892 to 1895 .

Life

Wilhelm Kohlrausch's father Rudolf Kohlrausch (1809-1858) was a physicist and from 1857 professor of physics at the University of Erlangen . His brother, Friedrich Kohlrausch (1840–1910) was a university professor in Zurich , Darmstadt , Würzburg and Strasbourg. His son Arnt Kohlrausch (1884–1969) was professor of physiology at the universities of Berlin , Greifswald and Tübingen .

Wilhelm Kohlrausch studied physics in Würzburg and was a student of August Kundt . He received his doctorate in 1879 in Würzburg on " About the experimental determination of the speed of light in crystals " and stayed at the Physics Institute there until 1883.

After a brief activity in 1882 as an assistant at the physics institute at the University of Strasbourg , he acquired an extraordinary professorship in theoretical physics. In 1884 he was appointed to the TH Hannover, where he held the professorship for electrical engineering from October 1, 1884. From July 1, 1892 to June 30, 1895 he was rector of the university and from 1899 to 1928 a member of the board of trustees of the Physikalisch-Technische Reichsanstalt (PTR) . He was also calibration inspector and on the technical advisory board of the Hanover tram company .

He retired in the winter semester of 1923, but represented his field of teaching until 1927. His successors were Karl Humburg and Harald Schering . Kohlrausch died on April 16, 1936 in Hanover.

In 1887 he was accepted into the German Academy of Sciences Leopoldina . He held the title of the Privy Councilor and an honorary doctorate Dr.-Ing. hc
