Australopithecus afarensis
In 1931 he joined the Nazi Party, and later undertook, partly on behalf of the Deutsche Forschungsgemeinschaft, expeditions to German East Africa in search of "primitive man". In 1938/1939 he discovered "Australopithecus afarensis" at Laetoli, without realizing the importance of his find. He also collected folklore of the Hadza and Isanzu.
