Hans Eppinger

Hans Eppinger Jr. (5 January 1879, in Prague, Royal Bohemia, Austria-Hungary – 25 September 1946, in Vienna) was an Austrian physician of part-Jewish descent who performed experiments upon Nazi concentration camp prisoners.

In the weeks before the Anschluss, Eppinger's house served as a quarter for the "Nazi student cells" at the University of Vienna, no different from that of the Viennese professors Wilhelm Falta and Hans Spitzy.

As a result of his experiments on concentration camp prisoners at Dachau, he gained a notoriety during World War II.

Along with professor Wilhelm Beiglböck [de], he performed tests on 90 Romani prisoners by providing them sea water as their only source of fluids.

However, in 2002, after Eppinger's association with Nazi prison camps had been brought to the attention of the Working Group for Planetary System Nomenclature by the Lunar Republic Society,[6] the name was dropped.
