Ernst Gustav Zaddach

Ernst Gustav Zaddach (7 June 1817, Danzig – 5 June 1881, Königsberg) was a German geologist and zoologist, who made contributions in the fields of carcinology and entomology. He is also known for his investigations of amber found in Samland (Baltic coast).

From 1836 to 1841 he studied sciences at the universities of Berlin and Bonn and later taught classes in natural history at the Collegium Fridericianum in Königsberg. In 1854 he became an associate professor, and in 1863 a full professor of zoology at the University of Königsberg.[1] In 1862 he was appointed director of the zoological museum in Königsberg.[2]

The amphipod species Gammarus zaddachi (Sexton, 1912) is named after him.[3]

gollark: Then I hooked it up to the actual mana-generation flowers and TNT-placement dispenser, and added some mana storage and a computer controller.
gollark: Most of it is a mana generator. For that, I looked at ways to make mana, then how to make the fuel each of them needed, and how I could make *that*, found one which seemed easiest, and then built small subunits for making each thing and connected them up.
gollark: What whole thing, the bunker or redstone generator?
gollark: It's already energy-shielded and reasonably blast-proof, but teleportation is a thing, so I'm thinking about putting some internal defenses.
gollark: I'm currently working on (in creative mode) this bunker thing, which will eventually (I hope) be able to produce all its components from scratch.
