Karl Haussmann

This article deals with the geophysicist Karl Haußmann. For other people see Karl Hausmann .

Karl Gottlob Friedrich Haußmann (born June 22, 1860 in Schwäbisch Gmünd ; † January 24, 1940 there ) was a German surveyor , geomagnetic and university professor .

Life

During his studies in 1881 he became a member of the Ulmia Stuttgart fraternity . Until 1886, Haussmann studied mathematics , mechanics and marrow science at the Technical University of Stuttgart as well as at the universities of Leipzig and Tübingen and was then a scientific assistant at the chair for geodesy and marrow study in Aachen and Stuttgart . After working as an engineer for a while, he became a private lecturer at the TH Stuttgart in 1896 . During this time he also married his wife Erwine Talmon-Gros . In 1899, Haußmann accepted a call as a full professor of mine surveying at RWTH Aachen , then in 1915 at TH Berlin . After ten years in Berlin, he retired and moved to his hometown. In 1917 he was elected a member of the Leopoldina . After his death he was buried in the Leonhard Cemetery.

Act

Haussmann was known for adapting student training to the changing demands of mining . To this end, he wanted to establish an institute for applied geophysics in Aachen in 1905 , but this failed due to a lack of money. In order to nevertheless achieve a certain research success in this area, he designed a program that could be implemented with the help of other institutes, including the measurement of the earth's magnetic field, especially from the mining perspective, seismic observations to assess the effects of earthquakes and traffic vibrations, Measurement of the elasticity constant of rocks etc., which led to the publication of maps of the geomagnetic elements in Germany in 1912. For a long time Haußmann's maps were the only source of this kind, which is why he worked on their further development until his death. The measurement of the geomagnetic field in southern Germany is seen today as a special achievement by Haußmann, for example in 1904 in the Nördlinger Ries and in 1932 in the Steinheimer basin .

Honors

Haußmann has received several awards, including:

• 1907: Red Eagle Order 4th class

• 1920: Honorary Doctorate ( Dr.-Ing. Eh ) of the Technical University of Aachen ,
• 1925: Honorary citizen of the Technical University of Berlin .
• 1928: Honorary doctorate in mining sciences from the Montanic University of Leoben
• 1930: Honorary member of the German Markscheider Association , in which Haußmann worked for a long time as editor, on the occasion of his 70th birthday
• 1935: Awarded honorary citizenship of his hometown Schwäbisch Gmünd
• Naming of Haussmannstrasse in the city center of Schwäbisch Gmünd
