D O C U M E N T S 4 , 5 J U N E 1 9 2 7 2 9 4. To Max von Laue [Berlin,] 12 June 1927 Dear Laue, Upon receiving your letter[1] I immediately spoke with Planck,[2] especially since I myself am so little involved in matters of appointment that I would in any case be unable to do anything on my own.[3] Planck says that the position must be offered first of all to Schrödinger.[4] This will happen and then everything will be worked out between him and you. I would prefer that you get the K. W. Institut.[5] As director, you would be able not only to provide stimulation but also create a hu- mane atmosphere. I would also go there gladly and often to participate as much as I can. Warm greetings from your A. Einstein P.S. Planck has a high opinion of you. Just let him handle this. 5. To Paul Ehrenfest [Berlin,] 13 June 1927 Dear Ehrenfest, I cannot visit you before the Solvay[1] Congress.[2] However, it also doesn’t have to be immediately afterward. I think the best thing would be for us to put off the visit until winter and set the date later on. I am making only slow progress in the search for singularities, but I am completely confident that it will succeed.[3] I am now hiring an assistant who will help me with the calculations.[4] Otherwise I waste too much time on mechanical matters. Warm regards from your A. Einstein
