Franz Hermann Troschel

Franz Hermann Troschel (10 October 1810 - 6 November 1882) was a German zoologist born in Spandau.

He studied mathematics and natural history at the University of Berlin, and beginning in 1840 was an assistant to Martin Lichtenstein (1780-1857) at the Humboldt Museum of Natural History in Berlin. In 1849 he became a professor of zoology and natural history at the University of Bonn.

Troschel is remembered for the identification and classification of species in the fields of malacology, ichthyology and herpetology. A few of the species that contain his name are Troschel's sea star (Evasterias troschelii), Troschel's parrotfish (Chlorurus troschelii), Troschel's murex (Murex troschelii) and freshwater snail Bithynia troschelii.
