Ernst Gustav Zaddach

from Wikipedia, the free encyclopedia

Ernst Gustav Zaddach (born June 7, 1817 in Danzig ; † June 5, 1881 in Königsberg ) was a German zoologist , entomologist and geologist .

Zaddach studied zoology in Berlin (with Johannes Müller , Christian Gottfried Ehrenberg ) and Bonn (with Ludolf Christian Treviranus and August Goldfuß ), where he received his doctorate in 1841 (De Apodis cancriformis Schaeffer, anatome et historia evolutioni). From 1841 he was a teacher of natural sciences at the Friedrichskolleg in Königsberg, where after his habilitation in 1844 he also taught zoology at the university, in 1853 became an associate professor of zoology and in 1863 a full professor. In 1862 he became director of the Zoological Museum. There he also built a hall with collectibles from East Prussia.

In contrast to his predecessors as zoology professors in Königsberg, Karl Ernst von Baer and Martin Heinrich Rathke , who focused on anatomy, he was more of a descriptive naturalist.

He dealt with crustaceans , among other things he was the first to describe the blood circulation in lower crustaceans, and as an entomologist with caddis flies and sawfly (his main work dealt with sawfly and wood wasps ). As a geologist, he dealt with the Tertiary of the Baltic Sea coast ( Samland ) and their amber deposits , whereby he was also concerned with economic exploitation. In 1868 he even officially received an order from the Prussian Ministry of Commerce to investigate the amber deposits in West Prussia and Pomerania.
