Notables: Arnold E. Ortmann

Ortmann was born in 1863 in Magdeberg, Prussia. He studied at the Universities of Kiel, Strassburg, and Jena. He received his PhD from the latter institution in 1885. Ortmann came to the United States in 1894 and was Curator of Invertebrate Paleontology at Princeton University. He left Princeton in 1903 to come to Carnegie Museum of Natural History. While still at Princeton, he worked on the Report upon the Tertiary Invertebrates of the Princeton Expedition to Patagonia.

Upon coming to Carnegie Museum of Natural History, Ortmann undertook extensive studies of the Decapoda: Crustacea. Following these studies, he began an intensive study of the unionids found in the drainage patterns on either side of the Appalachian Mountain Range. His work on the unionids resulted in several major monographs and numerous shorter papers. As early as 1909, Ortmann had commented on the effects of pollution in our waterways and its effect on the unionid populations. Ortmann's publication on the Naiads of South America was based primarily on material from the Haseman Collection. Haseman made this collection during an expedition to South America. At the time, it represented material from regions of the Amazon basin not yet explored by other scientists.

In addition to his duties at the museum, Ortmann was on the faculty of the University of Pittsburgh. He rose to the level of Professor and the University conferred the degree of ScD upon him in 1911. Ortmann died suddenly in 1927 at the age of 64. Upon his death, Stanley T. Brooks was appointed to care for the collection.
