Early life
Ludwig von Mises was born in the city of Lemberg, in Galicia, Austria-Hungary (now Lviv in Ukraine), to parents Arthur Edler von Mises from a recently ennobled Jewish family involved in building and financing railroads, and Adele von Mises (née Landau), the niece of Dr. Joachim Landau, a Liberal Party deputy to the Austrian Parliament. Arthur was stationed there as a construction engineer with Czernowitz railway company. At the age of twelve Ludwig spoke fluent Yiddish, German, Polish, and French, read Latin, and could understand Ukrainian. Mises had two younger brothers: applied physicist Richard von Mises, a member of the famous Vienna Circle, and later Karl von Mises, who died in infancy from scarlet fever. When Ludwig and Richard were children, his family moved back to their ancestral home of Vienna.
In 1900, he attended the University of Vienna, becoming influenced by the works of Carl Menger. Mises' father died in 1903, and in 1906 Mises was awarded his doctorate from the school of law.
Professional life
In the years from 1904 to 1914, Mises attended lectures given by the prominent Austrian economist Eugen von Böhm-Bawerk. There, he developed friendships not only with Menger and Böhm-Bawerk, but also prominent sociologist Max Weber. Mises taught as a
Privatdozent at the Vienna University in the years from 1913 to 1934 while formally serving as secretary at the Vienna Chamber of Commerce from 1909 to 1934. In these roles, he became one of the closest economic advisers of Engelbert Dollfuss, and, later, Otto von Habsburg. Friends and students of Mises in Europe included Wilhelm Röpke and Alfred Müller-Armack (influential advisors to German chancellor Ludwig Erhard), Jacques Rueff (monetary advisor to Charles de Gaulle), Lord Lionel Robbins (of the London School of Economics), and President of Italy, Luigi Einaudi.
Economist and political theorist F. A. Hayek first came to know Mises while working as Mises' subordinate at a government office dealing with Austria's post-World War I debt. Hayek wrote, "there I came to know him mainly as a tremendously efficient executive, the kind of man who, as was said of John Stuart Mill, because he does a normal day's work in two hours, always has a clear desk and time to talk about anything. I came to know him as one of the best educated and informed men I have ever known..." It was Hayek's development of Mises' innovative theoretical work on the business cycle which later earned him the Nobel Prize in economics.
In 1934, Mises left Austria for Geneva, Switzerland, where he was a professor at the Graduate Institute of International Studies until 1940. Fearing the prospect of Germany taking control over Switzerland, in 1940 Mises with other Jewish refugees left Europe and emigrated to New York City. There he became a visiting professor at New York University, from 1945 until his retirement in 1969, though he was not salaried by the university. Instead, he earned his living from funding by businessmen such as Lawrence Fertig. For part of this period, Mises worked on currency issues for the Pan-Europa movement led by a fellow NYU faculty member and Austrian exile, Richard Coudenhove-Kalergi. In 1947, Mises became one of the founding members of the Mont Pelerin Society.
In America, Mises' work first influenced that of economists such as Benjamin Anderson, Leonard Read and Henry Hazlitt, but writers such as former radical Max Eastman and novelist Ayn Rand were also among his friends and admirers. His American students included Israel Kirzner, Hans Sennholz, Ralph Raico, Leonard Liggio, George Reisman and Murray Rothbard. Mises later received an honorary doctorate from Grove City College.
Despite his growing fame, Mises listed himself plainly in the New York phone directory and welcomed students into his home. He retired from teaching at the age of 87, then, the oldest active professor in America. Mises died at the age of 92 at St. Vincent's hospital in New York.
