NOBEL PRIZE FOR PHYSICS - PHOTOGRAPHY - Gabriel LIPPMANN (1845-1921, French-Luxembourg physicist, Nobel Prize for Physics in 1908) / Correspondence of 2 autograph letters signed, totaling 6 p in-8, each on the letterhead of the Faculté de Sciences, Laboratoire des recherches à la Sorbonne, Paris, the addressee is not identified "Guérault", "Guéroust"?: 1°) On January 2, 1915, he thanks him for sending his book, which he will read with keen interest, "not only out of friendship for you, but because the subjects you deal with seem interesting to me, as we have not had the opportunity to discuss any of them between us, and I have always appreciated the solidity and sincerity of your reflections"; "my wife told me that you had thought of having her presented to the Académie des Sciences, and I shall be at your disposal to do so whenever you wish" (nb: daughter of Victor Cherbuliez, Laurence Lippmann was a collaborator of her husband and was very involved in the development of photography) - 2°) On February 16, 1915, he congratulated his friend, "your book is very interesting, we are no longer accustomed today to works that go beyond certain specialties, yours has the main quality of a book of great scope, it makes you think, that's all I have the leisure to tell you about it for the moment, we'll talk about it if you like; in the meantime, I don't know what could have made you think I'd judge it unfavorably - quite the contrary; I know even less why you imagine that our old and very solid friendship could have diminished, perhaps my long silence is the cause, so I must apologize; you know that in normal times we hardly have the time to see each other as I would like, today it's all over; one or two days after our conversation, I left for a rather painful trip, which I'll tell you about; on my way back I was caught up in my laboratory research on behalf of the public good, and I'm examining my other activities, so that the visit I was going to make to you on my way back has had to be postponed; I'm afraid I won't be able to have the pleasure of making it before next month; despite this, please be assured of my very cordial friendship".
