Eric Voegelin (1901–1985) was one of the most original and influential philosophers of our time. Born in Cologne, Germany, he studied at the University of Vienna, where he became a professor of political science in the Faculty of Law. In 1938, he and his wife, fleeing Hitler, immigrated to the United States. They became American citizens in 1944. Voegelin spent much of his career at Louisiana State University, the University of Munich, and the Hoover Institution at Stanford University. (from University of Missouri Press website)

"...He taught political theory and sociology at the University of Vienna after his habilitation there in 1928. 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.

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....

...Voegelin published several books and scores of essays and reviews in his lifetime. His magnum opus was the multi-volume (English-language) Order and History, which began publication in 1956 and remained incomplete at the time of his death 29 years later. His 1951 Charles Walgreen lectures, published as The New Science of Politics, is sometimes seen as a prolegomena to this, and remains his best known work. He also left many manuscripts unpublished, including a history of political ideas that has since been published in eight volumes...." (from Wikipedia.com)
