Hans Kelsen (/ˈkɛlsən/; German: [ˈhans ˈkɛlsən]; October 11, 1881 – April 19, 1973) was an Austrian jurist, legal philosopher and political philosopher. He was the principal architect of the 1920 Austrian Constitution, which with amendments is still in operation. Due to the rise of totalitarianism in Austria (and a 1929 constitutional change),[2] Kelsen left for Germany in 1930 but was forced out of his university post after the Nazi seizure of power in 1933 because of his Jewish ancestry. That year he left for Geneva and in 1940 he moved to the United States. In 1934, Roscoe Pound lauded Kelsen as "undoubtedly the leading jurist of the time". While in Vienna, Kelsen met Sigmund Freud and his circle, and wrote on social psychology and sociology.
By the 1940s, Kelsen's reputation was already well established in the United States for his defense of democracy and for his Pure Theory of Law. Kelsen's academic stature exceeded legal theory alone and extended to political philosophy and social theory as well. His influence encompassed the fields of philosophy, legal science, sociology, theory of democracy, and international relations.
Late in his career while at the University of California, Berkeley, although officially retired in 1952, Kelsen rewrote his short book of 1934, Reine Rechtslehre (Pure Theory of Law), into a much enlarged "second edition" published in 1960 (it appeared in an English translation in 1967). Kelsen throughout his active career was also a significant contributor to the theory of judicial review, the hierarchical and dynamic theory of positive law, and the science of law. In political philosophy he was a defender of the state-law identity theory and an advocate of maintaining an explicit contrast between the themes of centralization and decentralization in the theory of government. Kelsen also advocated separating the concepts of state and society in their relation to the study of the science of law.
The reception and criticism of Kelsen's work and contributions has been extensive with both ardent supporters and detractors. Kelsen's neo-Kantian defense of legal positivism was influential on H. L. A. Hart, Joseph Raz and other legal theorists in the analytical tradition of jurisprudence.
