SEVENTY PARK AVENUE HOTEL NEW YORK CITY TELEPHONE MANAGER LEXINGTON 2-7070 June 19, 1941 Professor Ludwig von Mises 599 West End Ave New York City Dear Professor: Since news in this country seem to circulate very fast, you might already have heard that I too have come here, about six weeks ago. The almost only remnants in Geneva are now the Guggenheims. I hope to have the opportunity of seeing you soon. In the meanwhile, I beg to introduce to you the bearer of this letter, Mr.Rudolf Lachmann Mosse, who is the son of a friend of my family. He came to New York in April and is looking around for some research work in the field of social science. Rudolf is a graduate from the University of Zurich; he wrote his doctor thesis with Professor M.Saitzew, on "Nitrogen Industry and its International Agreements. Fortunately, he is in a position to wait a little while until he finds remunerated work, so that he is not obliged to take any work which is not in his line, just for living purposes. He has had the privilege of hearing several of your lectures, but he is not known to you personally. Therefore he has asked me for an introduction to you, as he would very much like to consult you about his future. It is with great pleasure that I comply with his request, as I know him to be a very nace and capable young man, who would surely greatly benefit by any advice you might be willing to give him, and who certainly would not disappoint any person sponsoring him.
