We were all very much worried and shocked at the turn of events in Germany. I think it is an excellent idea for you to follow the invitation which takes you across the seas, and I only wish that you would accept my suggestion that I made to you a year ago, that you spend several years in the United States. If you would consider this possibility, I think arrangements could be made whereby you could have full independence and facilities to work. I do not think that matters will be very much different in Germany in the next few years. Will you let me know how you feel about this matter? I have had to abandon my trip to Germany for the reason that Mrs. Loeb was not very well and that it looked for a time as if she had to undergo a serious operation. I could not make up my mind to go to Germany with the burden of that worry rest- ing on my shoulders, and it seemed only fair to me that I should inform the com- mittee of this situation. It would have been a great satisfaction to me if I had had a chance to bring some of my results before the physical chemists, since I have a very limited audience in this country and since in Germany they are not familiar with the literature published during the year.[2] In addition, the opposition on the part of the majority of the biologists to any application of physical chemistry to biological problems, and the opposition of the old-fashioned type of colloid chemists like Wolfgang Ostwald,[3] prevent the dissemination of these facts in German literature. I hope it will be possible, finally, to get support in this country for those German scientists who are able to do the right kind of work if not, I am afraid there will be added to the brutality following this war the cessation of scientific activity which can only result in keeping the forces of brutality longer in power. I remain with kindest regards from all of us to yourself and Mrs. Einstein, Yours very sincerely, Jacques Loeb P. S.— I hope you will forgive me my dictating this letter in English. My handwrit- ing has become so illegible—probably on account of general weariness—that it will be easier for you to read this dictated letter in English than my own writing in German.
