The standard author abbreviation Apstein is used to indicate this person as the author when citing a botanical name . [1]
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 (1854–1931) at the zoological institute in Kiel. As a young man he carried out studies of freshwater plankton in Holstein lakes (1890–95). 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 (German Deep Sea 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 ("The Animal Kingdom"; from 1927). He was a member of the International Commission on Zoological Nomenclature, and from 1918 to 1945 was secretary of the Deutschen Zoologischen Gesellschaft (German Zoological Society).
In addition to his research involving the 1898–99 Deutschen Tiefsee-Expedition, he was tasked with processing material taken from the Plankton-Expedition (1889) and the Deutschen Südpolar-Expedition (1901–03). In his investigations, Apstein distinguished himself in research of Thaliacea.
Karl Hermann Johannes Thiele was a German zoologist specialized in malacology. Thiele was born in Goldap, East Prussia. His Handbuch der systematischen Weichtierkunde is a standard work. From 1904 until his retirement in 1925 he was the curator of the malacological collection at the Museum für Naturkunde in Berlin. Thiele described more than 1.500 new species of molluscs; until today their types are deposited with the Museum of Natural History in Berlin. Especially important are his works on the Mollusca of the First German Antarctica Expedition and of the German Deep Sea Expedition aboard the vessel Valdivia.

He travelled to South East Asia and the Caribbean as part of the 1899 deep-sea expedition. He coined the terms tropical rainforest and sclerophyll and is commemorated in numerous specific names.
Georg Adolf Otto Wüst was a German oceanographer. His pioneering work on the Atlantic Ocean provided a new view of the motions of water masses between the northern and southern hemispheres and the first evidence of the concentration of water mass spreading in western boundary currents.

The Valdivia Expedition, or Deutsche Tiefsee-Expedition, was a scientific expedition organised and funded by the German Empire under Kaiser Wilhelm II and was named after the ship which was bought and outfitted for the expedition, the SS Valdivia. It was led by the marine biologist Carl Chun and the expedition ran from 1898-1899 with the purpose of exploring the depths of the oceans below 500 fathoms, which had not been explored by the earlier Challenger Expedition.
