Carl Apstein
Carl Heinrich Apstein was a German zoologist.
In 1889 he earned his doctorate from the University of Kiel with a dissertation on the spinnerets of the orb-weaver spider. Afterwards, he worked as an assistant to Karl Brandt at the zoological institute in Kiel. As a young man he carried out studies of freshwater plankton in Holstein lakes. In May 1898 he obtained his habilitation at Kiel for zoology and comparative anatomy, and a few months later took part as a zoologist in the Deutschen Tiefsee-Expedition aboard the steamship "Valdivia".
In 1906 he was appointed associate professor in Kiel, and in 1911 became a scientific officer at the Preußischen Akademie der Wissenschaften in Berlin. In this position he worked as a publisher of scientific journals in the field of zoology, which included editorship of Das Tierreich. He was a member of the International Commission on Zoological Nomenclature, and from 1918 to 1945 was secretary of the Deutschen Zoologischen Gesellschaft.
In addition to his research involving the 1898–99 Deutschen Tiefsee-Expedition, he was tasked with processing material taken from the Plankton-Expedition and the Deutschen Südpolar-Expedition. In his investigations, Apstein distinguished himself in research of Thaliacea.Written works
