De generis humani varietate nativa.

Blumenbach was the founder of anthropology. In this, his doctoral dissertation, he classified mankind into four races, based on selected combinations of head shape, skin color and hair form. In the second edition (1781) he found it necessary to expand this division into five races, but his famous terms “Caucasian, Mongolian, Ethiopian, American, and Malayan” were not used until the third edition of 1795.
