Einstein,\" to Donald Hopf, in German, assisting in the sale of a violin, by offering to write a letter on his behalf, and by enclosing [not present] a suggestion from German-American musicologist, Alfred Einstein. 1 page, 4to. Princeton, 9 October 1940. Some fading to signature but quite legible. In full (translated): \"Dear Mr. Hopf, Enclosed is a suggestion of Alfred Einstein concerning the sale of the violin.  Perhaps you can provide a copy of the magazine and see whether there is an American edition (to save time).  Either you can write to the agent, or, if you prefer, I will do it gladly.  In this case, however, you must write me with more detail about the violin; write in such a way that one gets a clear picture.  In the hope of hearing from you soon, I am Yours Sincerely, Albert Einstein.\" \u003cbr\u003e\u003cbr\u003eKlaus Dietrich (K. Donald) Hopf (1918-1972) was the violinist son of Ludwig Hopf, Einstein's friend and physicist collaborator. The younger Hopf owned a 1771 violin by Giovanni Battista Guadagnini, which is possibly the violin mentioned in the present letter.","brand":"Schubertiade Music and Arts","offers":[{"title":"Default Title","offer_id":46093231325343,"sku":"4629","price":2200.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0512\/4826\/7423\/files\/Einstein_Violin_TLS_1.jpg?v=1722186737","url":"https:\/\/www.schubertiademusic.com\/products\/4629-einstein-albert-signed-letter-regarding-a-violin","provider":"Schubertiade Music and Arts","version":"1.0","type":"link"}
