Names like Menger, Böhm-Bawerk, Wieser, Hayek, and Rothbard are well-known to adherents of the Austrian school of economics. Emil Kauder isn't one of those names, but Murray Rothbard brings his contributions to Austrian thinking to light.
Many insights of Menger are nowadays part of standard economics. Many more are preserved in the distinct school of Austrian economics. This applies particularly to the notions of foresight and the role of uncertainty.
