Hans Thieme (10 August 1906 - 3 October 2000) was a German jurist and legal historian who became a university professor in 1938. His published output was, in aggregate, considerable, although he tended to prefer to present his research conclusions in articles - sometimes lengthy articles - published in learned journals, rather than in textbooks or monographs. Themes on which he focused included legal history in the context of German history, both medieval and modern, along with European humanism, law codifications and (German) Natural Law theory.
