D O C U M E N T 1 1 0 N O V E M B E R 1 9 2 5 1 3 1 an amicable meeting between your friend Planck,[9] who, so to speak, represents Germany and stands so prominently above the crowd in character, and Mrs. Curie could take place. That could occur very nicely if Mr. Planck and Mrs. Curie would accept our hospitality at the same time. We can fortunately make this possible be- cause, as you may remember, we have two rooms available for friends. This meet- ing would really be a symbol that would speak to the nations. We would not like to let such a fine opportunity as this, if it really does happen, pass by. So I wrote to Langevin and (because it is often not easy to reach him), when I did not receive an immediate response, to Perrin,[10] asking whether he thought that it would please Mme. Curie if we used this opportunity to invite Mr. Planck at the same time, which would lead to a meeting with her in our home setting. I wrote that as soon as I had a favorable response, I would suggest it to you, requesting that you please in- form me whether, in your opinion, Planck’s own sentiments would warrant that a longer stay in our household together with Mme. Curie could only be agreeable to him and Mme. Curie. If this is the case, I shall pose the pertinent question to Mme. Curie herself, which in the wake of the existing correspondence can most easily be done by telegraph through the mediation of Langevin and Perrin and after I have received your answer, I shall invite Mr. Planck, adding that Mrs. Curie will also be here. I am wholeheartedly committed to creating something that in my view would be very fine. You surely are also of the opinion that it would be a favor to the well- meaning world and above all to our Lorentz, during the celebration. I asked Perrin to send me a telegram: “You can proceed,” if his opinion is favorable. Perrin in- formed me by telegraph that I could proceed I hope my idea will fall on as good soil in Berlin for you to be able to send me the same telegram as well, allowing me afterward to simply invite Planck by telegram with you as intermediary.[11] Everything for the jubilee is coming along splendidly it remains in the simplest form but will nevertheless be full of inner grandeur. With warm regards, sincerely yours, H. Kamerlingh Onnes 110.
