Johann Friedrich Blumenbach

Johann Friedrich Blumenbach (11 May 1752 – 22 January 1840) was a German physician, naturalist, physiologist, and anthropologist. He was one of the first to explore the study of the human being as an aspect of natural history. His teachings in comparative anatomy were applied to his classification of human races, of which he claimed there were five, Caucasian, Mongolian, Malayan, Ethiopian, and American. He was a member of the Göttingen School of History.

Blumenbach's peers considered him one of the great theorists of his day, and he was a mentor or influence on many of the next generation of German biologists, including Alexander von Humboldt. Provided by Wikipedia
