Perhaps I am mistaken, but I have seen enough disappointments in this regard, and it would be painful for me to experience another one of this kind again. If I could obtain a teaching assignment, I would probably be allowed to continue working undisturbed in Potsdam, and such a position would also be healthy for me to the extent that I would be forced to think some material carefully through for the lectures, something I am unable to get to now. What do you think of this? I am staying here until the end of the week and am then driving to Ludwigshafen to view some preliminary work on the electric ovens for spectroscopic analysis,[8] and then via Frankfurt-am-Main, where I am going to visit Dr. Oppenheim,[9] homewards. Letters can reach me at Dr. Oppenheim’s address. I hope you and your stomach are doing well.[10] My wife[11] and I send you and your family our kind regards. Yours, E. Freundlich. 106. To Erwin Freundlich [Berlin,] 19 September [1919][1] Dear Mr. Freundlich, I just received your letter from your vacation.[2] I am very sorry that you cannot relax even during the summertime. First, as regards your booklet,[3] quite some cor- rection is in fact necessary if gross misunderstandings are to be avoided.[4] I shall be glad to talk everything over with you in conscientious detail upon your return. If we are not able to agree on the points, there is no great harm done, either in that case, my brief foreword endorsing it would just have to be omitted.[5] Did Campbell happen to make any exposures at the time[?] Were these total eclipses?[6] I did not know anything about it. You are entirely right that getting you a position in Potsdam should not be attempted for the present. The Gen. Th. of Rel. must win acceptance among astronomers beforehand. But I have the feeling it won’t be much longer now, unless completely unexpected things occur. The idea of a teaching assignment at the university quite appeals to me too, but probably won’t be easy to realize, either. I think I will check with Planck, though, as soon as he is back.[7]
