J. P. HAMILIUS Jr. Differdange, February 26th, 1952. Professor of Business & Economics 23, RUE DU STADION, 23 DIFFERDANGE (LUXEMBOURG) EUROPE PHONE 82-69 Professor Ludwig von Mises New York Dear Professor von Mises, I am indebted for the favour of your address to Mrs. Rose Wilder Lane, whose book THE DISCOVERY OF FREEDOM I have started translating in German and French. I take the liberty to ask you some informa- tions concerning liberalism. I am only 29 and had had to interrupt my studies for three years owing to the Hitler war. Mrs. Lane lastly suggested that I translate eventually in German and French your 11 Planned Chaos " of the Foundat. L. Economic Education. I then promised to see how things went with her book, but am more and more disposed to do these 60 or so pages beside Mrs. Lane's big book. As after all I am only a student of liberalism I beg you to let me know which books ( in English, French and German ) you advise me to read, the pro-liberals as well as the most intelligent and the most read socialists, planners and the like. I think it clever to read the enemies of liberalism too, because their books will supply me with interesting ideas as regards utopia of socialism, etc I have already most of your American-isuued books ( even two Germans: Kritik des Intervent. and Grundlagen der Nationalökonomie; as to " Liberalismus 11 I was informed some months ago by Fischer Jena, that " es auf Anordnung der Behörden makuliert werden musste If ), those of Hayek and Ropke. Please let me also know some time ( or tell me please where I can apply for those informations ) where I can get new or second-hand literature of older authors ( before World War I and II ). A French liberal wrote me last year - Un joli livre reste à faire: " Queet que le libéralisme ". Cela ne vous ten terait pas ? - The more I think of it, the more I get eager to do it. Once I shall have finished with Mrs. Lane's book., I am likely to start this great enterprise. Therefore I should like to get the most possible informations to prepare this work. I know very well English, French and German and some Italian and Dutch. So I can read most books in the original version.
