3 6 D O C U M E N T 1 6 J A N U A R Y 1 9 2 2 send me reprints of your papers since January 1918, perhaps also the reprinting at Teubner’s of your major papers on the general theory of relativity.[2] I need them most urgently because I have to forward them from Vienna and must have them on hand before February 1st. Please do not postpone this matter [3] I was unfortu- nately unable to write earlier because I was sick. I take this opportunity to ask you most kindly to send me a personal reference about the private lecturer and titular professor, Dr. Friedrich Kottler.[4] A number of Viennese gentlemen, Thirring[5] and I among them, intend to nominate the above-named ad personam as extraordinary professor of mathematical physics at our university. Considering that under the present precarious financial conditions such a proposal to the Ministry requires strong backing, an opinion from your quar- ters would be extremely valuable. I recall with pleasure those words you said about Kottler to me and Lampa[6] during your last Viennese stay. In once again expressing, in the name of my wife[7] as well as my own, the hope of seeing you and perhaps also your spouse at our home for a longer stay, I am, in pleasant anticipation of getting a message from you very soon, with best wishes, yours very truly, Ehrenhaft 16. To Maurice Solovine[1] Berlin, 14 January 1922 Dear Solovine, Much work and an aversion to book-writing make it impossible for me to write what you desire.[2] Soon you will receive my Princeton lectures.[3] That edition has to wait, though, until the same has appeared in America. Conditions for the pub- lisher: 20% of the retail price, thereof you get 5%, I the remainder. With cordial regards, yours, A. Einstein. D[ear] S[olovine], best would be if you wrote Mrs. Untermyer in English so that she sees that you can do so.[4] But you also have to tell her that you can do better in German and French. You also have to say that we spent much time together as young men and studied together.[5] Self-assured forthrightness is necessary every- where in America, otherwise you don’t get anything paid for and are looked down on.[6]
