Hugo Obermaier

Hugo Obermaier (29 January 1877, in Regensburg – 12 November 1946, in Fribourg) was a distinguished Spanish-German prehistorian and anthropologist who taught at various European centres of learning. Although he was born in Germany, he was later naturalized as a Spanish citizen in 1924. He is particularly associated with his work on the diffusion of mankind in Europe during the Ice Age, and in connection with north Spanish cave art, and resisted placing his science at the disposal of nationalistic and racialist interests in the Germany of the 1930s.
