I am sending you a young Bavarian, Count du Moulin, whose boundless enthusiasm for music and love of me brought him to Switzerland last year where he wanted my patronage, a thing which, as you know, I could not grant him as a teacher. By persistence and good behaviour he has at last got his family to allow him to follow my advice and go to Berlin to listen and to learn. Naturally I have no more in mind than just to introduce the young man to you, and I do so with the wish that you may take a fancy to him which he seems to me thoroughly to deserve. I cannot give him a direct introduction to Marx, as he wished, as that would be difficult and pointless from me, but I ask you to present him to Marx in my name, with the flattering remark, if you like, that he is the star which I commend to my protege. For the rest I don't think I have anything special to tell you. I feel sure that what I have said is enough to ensure your good advice and guidance for my man. Some time later, of course, you can send him on to Liszt.
