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, where he was awarded his doctorate in 1834. From 1840 to 1849 he was an assistant to Martin Lichtenstein at the Natural History Museum of Berlin. In 1849 he became a professor of zoology and natural history at the University of Bonn. In 1851 he became a member of the Academy of Sciences Leopoldina.
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 a freshwater snail ("Bithynia troschelii)".
