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.
