Hans Hahne (18 Mar 1875, Piesdorf–2 Feb 1935, Halle (Saale) ) was a German physician and prehistorian.
At the Universities of Jena, Munich, and Leipzig, he studied natural sciences and medicine and received his MD in 1899.
In 1902 Hahne settled in Magdeburg as an internist and neurologist, but closed his practice in 1905 to devote himself to prehistory and early history .
[1] Before 1933 Hahne joined the National Socialist Party and was Deputy District Culture Warden (Gaukulturwart), Director of Training in Racial Science (Rassenkunde) in Gau Mitteldeutschland (Saxony) of the SS Race and Settlement Main Office (Rasse- und Siedlungshauptamt).
In February 1934, Hahne suffered a severe stroke with paralysis on his left side, which hindered him so much that he had to turn over most of his duties to colleagues.
