German-born American political philosopher. He taught political theory and sociology at the University of Vienna after his habilitation there in 1928. While in Austria Voegelin established the beginnings of his long lasting friendship with F. A. Hayek. In 1933 he published two books criticizing Nazi racism, and was forced to flee from Austria following the Anschluss in 1938. After a brief stay in Switzerland, he arrived in the United States and taught at a series of universities before joining Louisiana State University's Department of Government in 1942. His advisers on his dissertation were Hans Kelsen and Othmar Spann.
Voegelin remained in Baton Rouge until 1958 when he accepted an offer by Munich's Ludwig-Maximilians-Universität to fill Max Weber's former chair in political science, which had been empty since Weber's death in 1920. In Munich he founded the Institut für Politische Wissenschaft. Voegelin returned to America in 1969 to join Stanford University's Hoover Institution on War, Revolution, and Peace as Henry Salvatori Fellow where he continued his work until his death on January 19, 1985. He was a member of the Philadelphia Society.
