During this time period, Hans Morgenthau departed from Germany to complete his habilitation dissertation in Geneva, which resulted in his book The Reality of Norms and In Particular the Norms of International Law: Foundations of a Theory of Norms.[25] By remarkable good fortune for Morgenthau, Kelsen had just arrived in Geneva as a professor and he became an adviser for Morgenthau's dissertation. The Pure Theory of Law is generally considered among the most original contributions made by Hans Kelsen to legal theory.
