Eberhard Fraas ( born June 26, 1862 in Stuttgart, † March 6, 1915 ) was a German geologist and paleontologist. He worked as a curator at the Stuttgart Natural History Collection and barg and edited the first scientist to the East African Mesozoic dinosaur fauna in present-day Tanzania.

Life

Eberhard Fraas was born on June 26, 1862 in Stuttgart, the son of Oscar Fraas ( 1824-1897 ), curator and professor at the geological and paleontological department of the Royal Natural History Cabinet. After high school he studied at the universities of Leipzig under Hermann Credner and Ferdinand circles and in Munich under Karl Alfred von Zittel, August Rothpletz (1853-1918) and Paul Groth. Here he received his doctorate in 1886 with a dissertation on the white starfish Jura. Due to its geological recordings in southern Karwendel mountains and the Wendelstein he published several writings and summed up his experiences, generally understood about the construction of the mountain in a book about the "scenery of the Alps" together.

In July 1888 he completed his habilitation at the University of Munich, in 1891 assistant at the Stuttgart Natural History Collection and 1894 curator of its geological, palaeontological and mineralogical department. The geological and paleontological exploration of his native Swabia he promoted through recordings of several leaves of geognostical special map Württemberg, through studies of Triassic, Jurassic and Tertiary Swabia and cave exploring. Compliance excited especially his studies on the structure and genesis of the Nordlinger Ries and the Steinheim basin, which he together with William Branco (later Wilhelm von Branca ) published.

Several trips to Spain, Sardinia, Italy, the Balkans, in western North America (1901 ) by Egypt and Syria (1897 ) and ( 1906) and ultimately to German East Africa (1907 ) expanded his horizon and filled it with new finds.

As a mining engineer Jurassic dinosaur discovered in East Africa, Fraas visited the locality as the first scientist. The findings brought by him and his publications were also the occasion of the soon after the Berlin Museum of Natural History then emitted Tendaguru successful expeditions. A number of Fraas ' Monographs treat the Labyrinthodontien, ichthyosaurs, plesiosaurs and crocodiles sea. His pedagogical talent led him to process the paleontological exercise book " The petrifacts collector ", which received wide coverage.

Fraas was also curator of the private mineral collection of Friedrich Alfred Krupp and taught from 1898 until his death in 1902 this self and its personal assistant Judicial grain in the natural sciences. Among other Fraas Krupp encouraged in his scientific commitment in marine zoology. Krupp had a price on the social application of the theory of evolution by Ernst Haeckel advertised.

Fraas was at the height of his work when he died on March 6, 1915 the aftermath of the drawn in East Africa dysentery.
