Hans Kelsen (; German: [ˈhans ˈkɛlsən]; October 11, 1881 – April 19, 1973) was an Austrian jurist, legal philosopher and political philosopher. He was the author of the 1920 Austrian Constitution, which to a very large degree is still valid today. Due to the rise of totalitarianism in Austria (and a 1929 constitutional change), Kelsen left for Germany in 1930 but was forced to leave his university post after Hitler's seizure of power in 1933 because of his Jewish ancestry.
