Over at the Circle Bastiat, Daniel J. Sanchez posted a video by Tom Woods interviewing Jeffrey Herbener. Herbener's career has been greatly influenced by one reference to Eugene Bohm-Bawerk. This is just one example of the importance of heterodox economics, even in neoclassical classes.
Professors are doing students and economics a huge disservice by focusing on the generic history of economic thought sequence from Smith-Ricardo-Mill-Marx-Marshall-Fisher-Keynes-Friedman-Samuelson. Of course each author added has an opportunity cost. Nevertheless, any generic history of thought book (my recommendation is here) can give this story. Hopefully, more and more teachers will branch out.
