PRINCETON UNIVERSITY INTERNATIONAL FINANCE SECTION (Department of Economics) P.O. Box 644 Princeton, New Jersey September 26, 1961 Professor Dr. Ludwig von Mises 777 West End Avenue New York 25, N. Y. Dear Professor Mises: I talked to Lawrence Fertig and invited him very cordially for the Friday meeting. Since his know- ledge of German is not adequate he asked to be excused, and I undertook to explain to you that his absence is neither due to a lack of our hospitality nor to a lack of his appreciation. I have written to Charlotte Friedman and hope she can make it. I learned that Gertrude Lovasy, of the IMF, would very much like to be present. You will remember that she was a member of the National- bkonomische Gesellschaft. I am calling her up to invite her. I probably have not fully explained the place of our meeting. You will find it described on the en- closed sheet. I have also reserved a double room for you at Lowrie House. If you come by train, please let me know so that I can meet you at the station. If you come by car, I wish you would call me as soon as you arrive. Our telephone number at home is: Walnut 4-2109; my office telephone number is Walnut 1-6600, extension 2102 (or 2101 if the first does not answer). Sincerely yours, Frilt Fritz Machlup
