 F.A. Hayek is one of the most important Austrians of the 20th century. He was Mises' colleague in Vienna and leader of his generation of the Austrian school, the only Austrian to win a Nobel Prize in economics. In Hayek's collected works, he devoted one volume called The Fortunes of Liberalism to essays on the history of the Austrian school and the impact of classical liberal thinking in Europe. So Hayek, of course, was there at the University of Vienna. He briefly met Karl Manger. He of course worked closely with Ludwig von Mises. And he was right in that milieu in the early Austrian school. And Hayek wrote several biographical essays on important Austrians like Manger and Mises. And they're collected in this volume of Hayek's collected writings. There's a second part of the book also that deals with Hayek's founding of the Montpelerin Society and his discussions of what happened in Europe before and after World War II when a liberty was at a low point not only in Europe but the US. So it's very instructive as we think about how we can bring about more liberty today.
