2007 Nobel Prize winner Leonid Hurwicz was a participant in the Ludwig Mises’ seminar at the Graduate Institute of International Studies in Geneva, Hurwicz tells us in his remarks commenting on a paper by Israel Kirzner published in the CATO Journal (pdf file). Hurwicz says he participated in the Mises seminar in the period 1938-1939. Curiously, Hurwicz also says he attended Hayek’s classes at the L.S.E. during the academic year 1938-1939. So it’s not fully clear just where Hurwicz was at any particular time during these years. Perhaps when Hurwicz has a bit more free time someone could contact him and get more information about this period and his experiences at this time.
In his comments on Kirzner Hurwicz says:
The ideas of Hayek (whose classes at the London School of Economics I attended during the academic year 1938â€”39) have played a major role In Influencing my thinking and have been so acknowledged. But my ideas have also been influenced by Oskar Lange (University of Chicago, 1940â€”42), as well as by Ludwig von Mises in whose Geneva seminar I took part during 1938â€”49 (sic).
This “49″ is certainly a typo and Hurwicz undoubtedly said “1938-1939″ — by the summer of 1940 Mises was fleeing for his life, and Hurwicz was in the United States.
