October 4, 1966 Mr. Henry Regnery President, Henry Regnery Company 114 West Illinois Street Chicago, Illinois, 60610 Dear Mr. Regnery: For several months I did not hear anything about the progress of Human Action. It may interest you that Doctor Robert A. Hessen wrote me on September 27: Next week, I begin teaching in the Graduate School of Business at Columbia University. At my suggestion, all of the eight teachers in the introductory course will be using chapter 15, "The Market" from Human Action as the first reading of the term. If this practice is continued, it will mean that each year approximately 500 future business- men will begin their graduate training by studying the nature of capitalism as expound- ed by you. Kindest regards
