From Oswald Veblen [Princeton,] 6 April 1922 Dear Professor Einstein, Thanks very much for your letter about Mr. Thomas.[1] He expects to leave for Germany early in June and to stay until September when he will return to this coun- try for a few months and then come back once more to Germany. I hope that you will find him a satisfactory student. He will at least be thoroughly familiar with your work on Relativity. Your manuscript arrived considerably later than your letter, but I finally received it and turned it over to Professor Adams.[2] The Princeton University Press is taking the steps necessary for its publication. With best greetings to yourself and Mrs. Einstein, I am, sincerely yours, Oswald Veblen. Translator’s note: Original written in English. 133.
