Franz Leopold Neumann, German lawyer and political scientist (born 1900)

Franz Leopold Neumann was a German political activist, Western Marxist theorist, and labor lawyer who became a political scientist in exile and is best known for his theoretical analyses of Nazism. He studied in Germany and the United Kingdom, and spent the last phase of his career in the United States, where he worked for the Office of Strategic Services from 1943 to 1945 writing the Secret Reports on Nazi Germany. During the Second World War, Neumann spied for the Soviet Union under the code-name "Ruff". Together with Ernst Fraenkel and Arnold Bergstraesser, Neumann is considered to be among the founders of modern political science in Germany.
