Friedrich August von Quenstedt

Friedrich August (from) Quenstedt ( born July 9, 1809 in Eisleben, † December 21, 1889 in Tübingen ) was a German geologist, paleontologist, mineralogist and crystallographer.

Life and work

Friedrich August Quenstedt studied from 1830 in Berlin by Christian Samuel Weiss " geology ". In 1837 he took over the newly created Department of Mineralogy and GeognoSIS at the Eberhard Karls University of Tübingen. He reasoned thus the young geology as an independent branch of science in the Kingdom of Württemberg. He served 52 years the chair. His tenure has been received as Quenstedt era in the annals of the Geological Institute. His research focused primarily on fossils and their use in stratigraphy. Through our own collections made, but also through acquisitions, he built in Tübingen on a significant, suitable for research and teaching collection of fossils. 1842 included the collection already 30,000 exhibits. A large part of this also contributed Öschinger farmers who collected ammonites for Quenstedt. In 1842 he coined the term landscape of stairs still used internationally.

Its main merit is the intensive study of the Jurassic formations of the Swabian Alb. For geological age determination he used as the Englishman William Smith index fossils. Named after him is the Quenstedtsche breakdown of fine layers of the Jura, which was replaced in 1973 by an international division. From his pen and the paleontological standard work comes the Jura, which he published in 1858. Until shortly before his death, he compiled an extensive panel work on the ammonites of the Swabian Alb. He knew how to interest by an entertaining lecture style to a wide audience for fossils. However, over Schwaben he looked out hardly. His fossil collection is now appreciated more in the Geological Institute of the University of Tübingen and can be used to compare their own findings. He was also in Nusplingen and discovered the Solnhofen.

One of his students was more important paleontologist Albert Oppel. His grandson Werner Quenstedt (1893-1960) was active in the 1930s and 1940s as a geologist and paleontologist at the Friedrich Wilhelm University in Berlin.
