Milton Friedman died this past week. He was the most influential economist of the 20th century when one combines his contributions to both economic science and to public policy. I knew him for many decades starting first when I was a graduate student at Chicago, and then as a colleague, mentor, and very close friend.
I will not dwell here on what a remarkable colleague he was. However, I do want to describe my first exposure to him as a teacher since he enormously changed my approach to economics, and to life itself. After my first class with him a half-century ago, I recognized that I was fortunate to have an extraordinary economist as a teacher. During that class he asked a question, and I shot up my hand and was called on to provide an answer. I still remember what he said, “That is no answer, for you are only restating the question in other words.” I sat down humiliated, but I knew he was right. I decided on my way home after a very stimulating class that despite all the economics I had studied at Princeton, and the two economics articles I was in the process of publishing, I had to relearn economics from the ground up. I sat at Friedman’s feet for the next six years– three as an Assistant Professor at Chicago– learning economics from a fresh perspective. It was the most exciting intellectual period of my life. Further reflections on Friedman as a teacher can be found in my essay on him in the collection edited by Edward Shils, Remembering the University of Chicago: Teachers, Scientists, and Scholars, 1991, University of Chicago Press.
