Karl Penka (26 October 1847, Mohelnice – 10 February 1912, Vienna) was an Austrian philologist and anthropologist.
Known for his now-outdated theories locating the Proto-Indo-European homeland in Northern Europe,[1] Penka has been described as "a transitional figure between Aryanism and Nordicism".
[2] Born in Müglitz, Moravia (now Mohelnice, Czech Republic), Penka was between 1873 and 1906 a master at the Maximiliansgymnasium, a high school for boys, in Vienna.
Penka popularised the theory that the Aryan race had emerged in Scandinavia and could be identified by the Nordic characteristics of blue eyes and blond hair.
In his 1883 book Origines Ariacae ('Origins of the Aryans'), he proposed that the Indo-European homeland was situated in the far north, corresponding to the Hyperborea of antiquity.
