Ludwig von Mises

In 1940, Mises emigrated from Austria to the United States to escape the Nazis. On the day German forces entered Vienna, they raided his apartment, confiscating his papers and library, which were believed lost or destroyed until rediscovered decades later in Soviet archives. At the time, Mises was living in Geneva, Switzerland. However, with the imminent Nazi occupation of France threatening to isolate Switzerland within Axis-controlled territory, he and his wife fled through France—avoiding German patrols—and reached the United States via Spain and Portugal.
Since the mid-20th century, both libertarian and classical liberal movements, as well as the field of economics as a whole have been strongly influenced by Mises's writings. Mises's student Friedrich Hayek viewed Mises as one of the major figures in the revival of classical liberalism in the post-war era. Hayek's work ''The Transmission of the Ideals of Freedom'' (1951) pays high tribute to the influence of Mises in the 20th-century libertarian movement. Economist Tyler Cowen lists his writings as "the most important works of the 20th century" and as "among the most important economics articles, ever". Entire schools of thought trace their origins to Mises's early work, including the development of anarcho-capitalist philosophy through Murray Rothbard and the contemporary Austrian economics program led by scholars such as Peter Boettke at George Mason University.
Mises’s most influential work, ''Human Action: A Treatise on Economics'' (1949), laid out his comprehensive theory of praxeology—a deductive, a priori method for understanding human decision-making and economic behavior. Rejecting empirical and mathematical modeling, Mises defended classical liberalism and market coordination as products of rational individual action. Beyond his published works, Mises shaped generations of economists through his longstanding private seminar in Vienna and later as a professor at New York University. His ideas deeply influenced students such as Friedrich Hayek, Murray Rothbard, and Israel Kirzner, who helped inspire the rise of postwar libertarian institutions in the United States, including the Foundation for Economic Education and the Ludwig von Mises Institute.
Mises received many honors throughout the course of his lifetime—honorary doctorates from Grove City College (1957), New York University (1963), and the University of Freiburg (1964) in Germany. His accomplishments were recognized in 1956 by his alma mater, the University of Vienna, when his doctorate was memorialized on its 50th anniversary and "renewed", a European tradition, and in 1962 by the Austrian government. He was also cited in 1969 as "Distinguished Fellow" by the American Economic Association. Provided by Wikipedia
