Ernst Weinschenk (Munich, 1909)

Ernst Heinrich Oskar Kasimir Weinschenk (born April 6, 1865 in Esslingen am Neckar , † March 26, 1921 in Munich ) was a German mineralogist and petrologist .

biography

Weinschenk was the son of a royal Württemberg regional court president and, after graduating from Karls-Gymnasium Stuttgart , studied natural sciences in Tübingen , Leipzig and Munich with a focus on geology and mineralogy. From 1884 he was a member of the Catholic student association AV Guestfalia Tübingen . He received his doctorate summa cum laude from Paul Heinrich von Groth in Munich in 1888 with the dissertation on the transformation of quartz into soapstone . Weinschenk also studied in Greifswald, Paris and London. From 1897 he was Professor of Petrography at the Technical University of Munich and from 1900 Associate Professor at the University of Munich.

Weinschenk had three sons and two daughters with his wife Elsa Lechner. He died of complications from a gallstone operation.

Weinschenk became known for his studies of the mineralogy of meteorites and contact metamorphosis in the Alps. He was a pioneer in the use of thin sections and the polarizing microscope, with which he discovered many new minerals. He investigated the formation of the Silberberg sulfur ore deposit in the Bavarian Forest and graphite deposits near Passau (in particular Kropfmühl , Hauzenberger graphite ), which he attributed to exhalative formation in connection with granite orogenesis (which in the case of graphite deposits was soon from Hans Cloos and others).

In addition to his own works on petrology, he published the 6th and 7th editions of Franz von Kobell's textbook on mineralogy .

The mineral Weinschenkit is named after him.
