Bernhard von Cotta
Carl Bernhard von Cotta ( born October 24, 1808 Forest House Small Zillbach; † September 14, 1879 in Freiberg ) was a German geologist and mining researchers.
Life
The son of the forest scientist Heinrich Cotta studied since 1827 Mineralogy and Geology at the Freiberg, where he joined in 1829 the Corps Montania. From 1831 he studied at the Ruprecht -Karls- University of Heidelberg, where he received his doctorate in 1832, and at the Academy of Forestry Tharandt. After completing his studies Cotta received in 1839 a position as secretary to the Academy of Forestry.
As early as 1832 he collaborated on the publication of the geognostical Map of Saxony. First, under the direction of Carl Amandus Kühn, took Cotta from 1835, together with Carl Friedrich Naumann, the line of work.
In 1842 he took over after the departure of Naumann in Leipzig whose Department of geology at Freiberg and completed in 1845, the Geognostic Map of Saxony. Inspired by the popular by Louis Agassiz Ice Age theory, he also found east of Leipzig traces of glaciers, which impressed him greatly near the Hohburger mountains: "Should the Nordic glaciers really have ranged from the Scandinavian mountains to the Wurzener hill? I am cold at the thought. " Cotta extended his lecture even to the regions of the Versteinerungslehre and Erzlagerstättenlehre. In 1848 he was one of the founding members of the Geological Society.
As a participant in the March Revolution Cotta in 1849 pardoned. While his father Heinrich Cotta had always refused to renew the original title of nobility of the family, it was his three sons, Bernhard, William and August 1858 newly awarded on application.
Bernhard von Cotta's investigations were limited not to Germany. He described in 1854 the ore deposits in Transylvania, Hungary, the Banat, Serbia, Bukovina and in the Eastern Alps. On behalf of the Russian Tsar Alexander II in 1868, he traveled to the Altai.
Cotta, who was Bergrat since 1862, occurred in 1874 in retirement. His successor was Alfred Wilhelm Stelzner. Cotta died 1879 in Freiberg and was buried in the cemetery Donat.
