August Leppla

from Wikipedia, the free encyclopedia

August Leppla (* 12. August 1859 in Matzenbach at Glan ; † 12. April 1924 in Wiesbaden ) was a German geologist who around the turn of the century from the 19th to the 20th century as a country geologist at the Prussian Geological Survey in Berlin important work in the geological survey of Prussia . Many of the geological maps of the Rhenish Slate Mountains that exist today go back to Leppla. Leppla was one of the first to examine the technical properties of rocks . In the area around his Palatinate homeland and the wider area around Wiesbaden, he also earned services in issues of water supply and dam construction .

Life

August Leppla was born in 1859 to the miller couple Jakobina and Peter Leppla. He had eight siblings and August was the sixth child. After primary school in Matzenbach, he attended the district secondary school and industrial school in Kaiserslautern and then studied engineering at the Technical University of Aachen . He then passed the state examination in descriptive natural sciences in Munich in 1880 . Leppla spent the next two years in Strasbourg, studying mineralogy and geology. He completed his academic years with a doctorate at the University of Freiburg on Remigiusberg near Kusel and in 1883 became an assistant at the Bavarian Mining Authority in Munich. In 1888 he accepted a position at the Prussian State Geological Institute in Berlin. In 1894 he rose to the position of district geologist and in 1900 finally to the Prussian state geologist.

Act

His scientific work began with mapping work in the Palatinate while he was still at the Oberbergamt in Munich. As a district and state geologist, he initially worked primarily in the area between the Saar , Nahe and Mosel and in Hunsrück and Eifel . In the mid-1890s he investigated the risk of flooding in the area of ​​the Glatzer Neisse in Silesia and wrote an extensive treatise on it that appeared in 1900. With the completion of the work in Silesia, he turned back to the geological investigation of the vicinity of his home region and worked in the Taunus and Rheingau . By moving to Wiesbaden, he lived in the middle of his preferred field of work and gained the reputation of an outstanding expert on the geology of Nassau .

With the beginning of the First World War he was drafted into the military and served as a military geologist . In the post-war period he resumed his research. Furthermore, his work concentrated on the southeastern Rhenish Slate Mountains, one of his main focuses were the mineral springs that are common in this area . In addition, he began to reorganize the mineral collection of the Natural History Museum in Wiesbaden , which led to the public inauguration of the collection in 1920. In the same year Leppla took over the chairmanship of the Nassau Association for Natural History , which he held until his death. August Leppla was a member of the Geological Association and since 1881 a member of the German Geological Society .

In addition to his geological services, he made a living as a local historian and founded the Palatina Library , which is now part of the Palatinate Library of the Palatinate District Association .

Honors

Leppla was appointed professor in 1906 because of his special scientific achievements; in the same year he was elected a member of the Leopoldina . In 1911 he received the Red Eagle Order of the IV class and in 1913 was promoted to the Secret Mountain Ridge. The Society for Natural Research in the Palatinate ( Pollichia ) honored his services to geological and mineralogical research in the Palatinate with his appointment as an honorary member.

Geological maps

Leppla carried out the mapping of a whole series of geological maps and wrote the explanations for them. Most of the map sheets are in the Taunus, but some also in the Hunsrück and South Eifel. The publication of the maps spanned the period from 1899 to 1930, as some of the maps were only published after his death. He played a major role in the following map sheets:
