Arnold Edward Ortmann

from Wikipedia, the free encyclopedia

Arnold Edward Ortmann , originally Arnold Eduard Ortmann , (born April 8, 1863 in Magdeburg , † January 3, 1927 in Pittsburgh ) was a German-American zoologist. Its official botanical author abbreviation is " AEOrtmann ".

Life

Ortmann was the son of a high school teacher, went to school in Magdeburg and Schleusingen and studied natural sciences in Jena and Kiel from 1882 (1884/85). Ernst Haeckel was one of his teachers in Jena . In 1885/86 he was an assistant at the botanical institute in Jena, where he received his doctorate in 1885 (contributions to the knowledge of underground stem structures) and was assistant at the Zoological Museum in Strasbourg from 1887 to 1894. In 1894 he went to the United States and was a curator for invertebrate paleontology at Princeton University , where he also taught physical geography. In 1900 he became a US citizen. In 1903 he became curator of invertebrate zoology at the Carnegie Museum of Natural History in Pittsburgh. He was also from 1909 instructor for animal geography and 1910 to 1925 professor of physical geography and then for zoology in Pittsburgh.

In 1890/91 he took part in an expedition to German East Africa (Zanzibar) with Haeckel and in 1899 in the Princeton University expedition to Greenland ( Peary Relief Expedition).

He dealt mainly with invertebrates in freshwater and marine, both fossil and recent species. In particular, decapods and other crustaceans (especially crayfish), moss animals , hard corals , cephalopods and mollusks , for example freshwater mollusks from US rivers such as the Ohio River and the Mississippi. He also dealt with animal geography. He formulated a law named after him, according to which mussels in a river have different appearance depending on the place in the river where they settle. This had an impact on the classification of mussels, as they were often assigned to different species beforehand. Ortmann also dealt with botany.

In 1912 he became a member of the Leopoldina . He published autobiographical material in the Festschrift for the 70th birthday of Ernst Haeckel (memoranda of med.-naturwiss. Gesellschaft Jena 1904). In 1911 he received his doctorate again in Pittsburgh (D.Sc.).

In 1894 he married Anna Zaiss, with whom he had a son and two daughters.
