MARQUETTE UNIVERSITY THE ROBERT A. JOHNSTON COLLEGE OF BUSINESS ADMINISTRATION MILWAUKEE 3, WISCONSIN August 25, 1961 Professor Ludwig von Mises New York, N.Y. Dear Professor von Mises: I am very sorry that I shall not be able to attend this meet- ing and, therefore, not be able to express my thoughts and feelings in person. These few lines can serve only as a poor substitute of what I want to say. I wish to express my thankfulness to your for all I learned from you (and very much of it in the Privat seminar), and for your unfailing kindness and forbearance. Most of what I have ever learned in Economics I learned in the Privat seminar, and there has been very little to change and to revise since. Above all I have learned, and I am thankful f or it, what scholarship requires: the development of ideas without regard to persons, times, and surroundings, the greatest regard for the correctness of thought combined with the greatest tolerance as to the persons who think differently. This is more than the technical details, which come with it. I have never found a place in the United States comparable to the Privat seminar. Let me, then, thank you for everything, and please accept my best wishes - ad multos annos. Yours very sincerely, Waller Breakerl Walter Froehlich WF:sg
