Ludwig Heinrich Edler von Mises (Galicia, Austro-Hungary, 29 September 1881 – New York City, 10 October 1973) was an Austrian-American economist, philosopher, and classical liberal. He was of Jewish descent and a prominent figure in the Austrian School of economic thought.
Fearing a Nazi take-over of Europe, Mises emigrated to New York in 1940. He published his most famous work Human action in 1949. Mises had a big influence on the Libertarian movement that developed in the United States in the mid-20th century.
