# Alexander Tornquist

Alexander Tornquist (18 June 1868 in Hamburg – 1 November 1944, Graz) was a German-Austrian geologist, who is known for his work on the northern part of the Trans European Suture Zone and on Mediterranean geology.

## Biography

Alexander Tornquist was son of the merchant Alexander Heinrich Tornquist and Minna Mathilde Tornquist, née Fett. He studied at the universities of Freiburg, Munich and Göttingen. In 1892 he received a PhD in geology and paleontology at the university of Göttingen. In 1901 he obtained an associate professorship for geology and paleontology at Strasbourg, and in 1907 became a full professor at Königsberg. In Königsberg he also served as director of the famous Prussian amber collection and of the institute of seismology. He spent his later life in Graz, where he had a professorship at the Technische Hochschule from 1914 onward. From 1915 to 1918, he served as dean to the chemo-technical faculty. From 1924 to 1926, Tornquist was rector of the Technische Hochschule. Tornquistʹs bona fide involvement and expertise in the so called West-Styrian beryl-scandal around fraudster Emil Johann Paul Mehling (alias Dr. Kurt Seidler) in the years 1929/30 lead to his early retirement from the university in 1933.
In 1897, Alexander Tornquist married Anna Elisabeth Henze, who was born on 9 February 1877 in Dresden and daughter of a sculptor. They had five children. Their daughter Erika (1903–1962) was married to Caspar Neher who is known for his lifelong cooperation with Bertolt Brecht. Alexander Tornquistʹs son Martin Wolfgang Tornquist (born on 31 May 1900 in Strasbourg) was a painter and studied at the Academy of Fine Arts, Munich, where he befriended Neher. Martin was diagnosed with schizophrenia in 1925, repeatedly admitted to different psychiatric institutions and not released after a stay at the end of 1940. He died on 11 February 1945 becoming thus a victim of so-called euthanasia.
Alexander Tornquist died in 1944 during an air raid on Graz, together with his wife and his sister Ellen Tornquist, who was born on 24 June 1872 in Hamburg and worked as a painter.
