D O C U M E N T S 9 8 , 9 9 M A R C H 1 9 2 2 1 0 9 P.S. Mrs. Ménard-Dorian is very aggrieved that you will not be staying with her. She has a charming house and she herself is an élite woman who knows how to spend her great fortune without offending the democratic spirit. 98. From Leo Jolowicz Leipzig, 20 March 1922 Highly esteemed Professor, Dr. Löwe is out of town. Perhaps you could mark the items in the enclosed cat- alog that you consider important for “Jerusalem” University I shall be happy to donate them. At the same time, I cord[ially] request of you, esteemed Professor, the address or the name of your young collaborator who is supposed to bring your relativity theory up-to-date again. If you do not know his address, then just give us his name we will then find out the address, all right. Best compliments & many thanks, yours very sincerely, Akademische Verlagsgesellschaft m.b.H. Leo Jolowicz. 99. From Paul Langevin Paris, 20 March 1922 My dear Friend, We are all overjoyed at the idea of soon having you here I am busy organizing the meetings of the Collège for the dates I indicated to you. I transmit in attachment a letter by Mr. Xavier Léon on the subject of the meeting that he requests of you for the Société Française de Philosophie on 6 April. He would be pleased if you could give him a title for publication to open the dialogue, and a few lines of “theses” as an agenda. If the planned invitations are convenient for you, would you please immediately reserve the following dates: Saturday, 1st April for lunch at Sir Thomas Barclay’s (at noon). Sunday, 2 April for lunch in Boulogne on the Tour du Monde premises (noon). Wednesday, 5 April for dinner (7 o’clock) at the home of Mr. Borel. I think I have reserved Thursday for a program of discussions acceptable to some colleagues and will submit it to you directly. See you soon, and most affectionately yours, P. Langevin.
