Emil Lehmann (mineralogist)

from Wikipedia, the free encyclopedia

Emil Lehmann (born January 25, 1881 in Ittenheim , Alsace , † January 11, 1981 in Garmisch-Partenkirchen ) was a German mineralogist and petrologist.

Life

Lehmann attended grammar school in Strasbourg and then in 1901/2 did an internship ( Bergbaubeflissener ) at the Oberbergamt in Bonn, where he visited ore and coal mines in the Rhineland, the Saar region and on the Lahn. From 1902 he studied at the University of Strasbourg , the Humboldt University in Berlin and the Berlin Bergakademie, where he graduated as a mountain trainee in 1906. In 1908 he received his doctorate in Berlin ( petrographic investigations of igneous rocks from the island of Neupommern ) and from 1907 he was assistant at the Mineralogical-Geological Institute of the TH Danzig , where he qualified as a professor in 1911 ( foundations of a new systematics of igneous rocks). During this time he also studied magnetite deposits in northern Spain, iron ore deposits in Sweden and in 1912/13 gold mines in Siberia (Garewka gold mines).

In 1914 he was at Immanuel Friedlaender's Research Institute for Volcanology in Naples. During the First World War he was an officer in the railway troops. He then went to the University of Halle , where he completed his habilitation and became an associate professor in 1924. In addition, he managed the chemical factory of the iron and steel works in Berlin-Tempelhof until 1926, when he became professor for mineralogy and petrography at the University of Giessen . From 1939 to 1945 he did military service again in World War II. He was also a member of the NSDAP .

Lehmann stayed at the University of Giessen until his retirement in 1954, which was closed from 1946. There he mainly dealt with the iron ores and igneous rocks in the Lahnmulde as well as with the formation of basalts (differentiation, crystallization). A rock designation proposed by him in 1941, Weilburgite , did not prevail (they are partly attributed to diabases and partly to scarf stones, Lehmann saw them between diabases and keratophyres).

He spent his retirement in Garmisch-Partenkirchen, but continued to publish until 1979.

He had been an honorary member of the German Mineralogical Society since 1971 .
