Mises was chief economist for the Austrian Chamber of Commerce and was an economic adviser of Engelbert Dollfuss, the austrofascist but strongly anti-Nazi Austrian Chancellor,[7] and later to Otto von Habsburg, the Christian democratic politician and claimant to the throne of Austria (which had been legally abolished in 1918).[8] In
1934, Mises left Austria for Geneva, Switzerland, where he was a professor at the Graduate Institute of International Studies until 1940.

Engelbert Dollfuss (German: Engelbert Dollfuß, IPA: [ˈɛŋəlbɛʁt ˈdɔlfuːs]; October 4, 1892 – July 25, 1934) was an Austrian Christian Social and Patriotic Front statesman. Having served as Minister for Forests and Agriculture, he ascended to Federal Chancellor in 1932 in the midst of a crisis for the conservative government. In early 1933, he shut down parliament, banned the Austrian Nazi party and assumed dictatorial powers. Suppressing the Socialist movement in February 1934, he cemented the rule of “austrofascism” through the authoritarian First of May Constitution. Dollfuss was
assassinated as part of a failed coup attempt by Nazi agents in 1934. His successor Kurt Schuschnigg maintained his regime until Adolf Hitler's annexing of Austria in 1938.
