Life

Credner was the eldest of the four sons of the government assistant and later mountain councilor Heinrich Credner and his wife Anna née. Vey. After graduating from high school, he studied mining at the Bergakademie Clausthal , then mineralogy , geology and paleontology at the Silesian Friedrich-Wilhelms-Universität . In 1863, like Eugen Hahn and Hermann Maas, he was recipients of the Corps Silesia Breslau . Finally he moved to the Georg-August University in Göttingen . In 1864 he was awarded a Dr. phil. PhD . In 1865 he went to the United States to study . Here Credner earned his living as an appraiser for track construction and gold mines .

After he returned from America in September 1868, he completed his habilitation thesis and in 1869, under Carl Friedrich Naumann, became a private lecturer in geognosy and paleontology at the University of Leipzig . In 1870 he was appointed associate professor of geology and paleontology. In the same year Credner took part in the Franco-German War as a department leader in the medical corps. After the war he continued his academic career at the University of Leipzig. In 1877 he was appointed full honorary professor. In 1895 Credner took over the newly created chair for geology and palaeontology at the Faculty of Philosophy.

In 1872 Hermann Credner was entrusted with the geological survey of Saxony . For this he was appointed director of the later Saxon Geological State Office. The task consisted of the exact geological mapping of the Kingdom of Saxony in 127 map sheets. The geological survey of the state was almost completed by 1895 under Credner's direction. 123 maps were created (the remaining maps included the border areas between Saxony and Prussia and were developed later). This was the first time that a comprehensive special geological map of Saxony was available. From 1875, Credner also devoted himself to earthquake observation in Saxony. It is thanks to him that an earthquake station was opened in Leipzig in 1902 with the support of the Saxon government .

Credner was married to Marie Riebeck, daughter of the industrialist Carl Adolf Riebeck, since 1872 . The marriage resulted in six daughters.
