Felix Kopstein

Felix Kopstein (4 June 1893, Vienna – 14 April 1939, The Hague) was an Austrian-Dutch physician and naturalist, known for his work in the field of herpetology.

From 1913 to 1920, he studied biology and medicine at the University of Vienna, during which time he made the acquaintanceship of zoologist Otto von Wettstein. In 1914 he collected herpetofauna specimens in Albania. From 1921 onward, he was assigned as a physician in the Dutch East Indies, being based on the island of Amboina, from where he made several zoological excursions to New Guinea and throughout the Moluccas. In 1924 he transferred to Java, being employed at the Pasteur Institute in Bandung, while in the meantime conducting studies of lizards and snakes native to the island.

His name is associated with Kopstein's bronzeback snake (Dendrelaphis kopsteini) as well as Kopstein's emo skink (Emoia jakati), a species described by Kopstein in 1926. Also, through a trilingual play on words, he is honored in the specific name of another skink, Sphenomorphus capitolythos, in the following way: capito + lythos (Greek) = "head" + "stone" (English) = Kopf + Stein (German).
