General Karl Haushofer (1869 - 1946) popularised geopolitics, notably in the Nazi regime. Some researchers think that by the contact of his student Rudolf Heß, Haushofer had considerable influence on the development of Hitler's ideas of expansion. Haushofer denied strong influence on the Nazi regime and committed suicide in 1946. His son, Albrecht, was killed by the Nazis because of opposition to the government.
