Wilhelm Röpke (1899-1966) was schooled in the tradition of the Austrians and made enormous contributions to the study of political institutions. His powerful anti-Keynesian writings in particular underscore what an outstanding economist he was and the extent to which he was influenced by Mises. Röpke defended sound money and free trade, and attacked welfare. While some consider him a doubter on free markets, he was in fact a passionate advocate of laissez-faire.
Ludwig von Mises: "Only stilted pedants can conceive the idea that there are absolute norms to tell what is beautiful and what is not. They try to derive from the works of the past a code of rules with which, as they fancy, the writers and artists of the future should comply. But the genius does not cooperate with the pundit." - Theory and History
