| Dathe, Johann Friedrich Ernst
German geologist and teacher. He was preparing for his teaching career in Nossen between 1863 and 1865, later he taught at several places. In 1876, he quit teaching and dedicated his career to the studies of natural science at the University of Leipzig, a place where many renowned scientists used to work, such as H. Gredner, A. Schenck, F. Zirkel. He completed his studies in 1873,having defended a thesis on microscopic investigation of diabases, and joined the newly established office 'Geologische Landesuntersuchung von Sachsen'. He was in charge of the project investigating the Granulite Mountain Range, of which results he summarized after a six-year research and mapping in the papers 'Die Diallaggranulite der sächsischen Granulitformation' and ' Beiträge zur Kenntnis des Granulits'. In 1880, he started working as junior geologist at the Prussian Geological Provincial Institute, responsible for special mapping of Silesia. In 1887, he was promoted to a position of regional geologist and in 1889 he was ordered to investigate geology of mineral springs in Salzbrunn. These studies resulted in compilation of a special map of wider area accompanied with extensive explanatory notes. He devoted his other studies to the Soví hory Mountains and Silesian 'Flözgebirge '.The was interested in areas, which were exposed to glaciation. He came to the conclusion that the continental glacier on the edge of the Soví hory Mountains attained a minimum height of 560 meters and, through lower lying passes, penetrated deep into the Kladsko Basin. He was also resolving practical geological problems in construction industry, protection of curative springs, water supplies, and was involved in consulting. The fossil Datheosaurus macrura SCHROEDER (ichthyostegid, Permian) is named after him. |
