Albert CALMETTE (1863-1933) bacteriologist. 18 L.A.S., Lille and Paris 1903-1931, to Dr. Maurice de Fleury; 29pages in-8 or in-12, headed Institut Pasteur de Lille then Institut Pasteur. Very interesting medical correspondence on the Institut Pasteur, his own work, and the Académie de Médecine. He thanks his friend for his congratulations after his election to the Académie des Sciences, gives news of Gaston, whose state of health worries him, accepts his invitation to come and discuss with him and Grancher; thanks to his intervention, he was admitted to the Tuberculosis Commission; the discussion also revolves around Maurice de Fleury's candidacy for the Académie de Médecine: they play off their influences and count their votes. He is reassured by Charles Monod's comments about him. "I've never tried to be unpleasant to him in any way, and I've always loudly proclaimed my respect for his character and talent. But I foresaw myself being rather unsympathetic to him, for I could not otherwise explain his attitude towards me at the Paris International Conference: M. Étienne told me of his opposition to my appointment as delegate to this conference, and the argument he put forward (that I was of the opposite opinion to Roux in matters of sanitary prophylaxis, and that it would be deplorable to put us in contradiction on this occasion, etc.) was so extraordinary and contrary to the truth, that I looked in vain for the real causes of my disgrace! You would be most agreeable to me if you could persuade him to confirm his feelings of esteem and sympathy by keeping the promise he made me so long ago to come and see me in Lille"... He organizes Fleury's visit to Lille with Monod. "We'll have lunch and then visit the Institute and my experimental wastewater treatment facility, which will be of interest to both of you". He answers his questions. "1° I don't know that Otto electrostabilizers have ever proved themselves. They failed miserably in the experiments organized three months ago by the Paris public assistance service. They cannot therefore be considered effective. 2° We have never succeeded in disinfecting apartments using the various processes of atmospheric ozonification. To be antiseptic, ozone must be present in the air at a dose of 4 to 5 milligrams per liter of air, and at this dose, the air is absolutely unbreathable. Moreover, the production of ozone at this concentration is too costly to be practical in this particular case"... The negotiations continue for the Académie de Médecine, and the cross-applications embarrass him. "I am bound to extreme reserve for a host of reasons, the main one being that it would be shocking to see one of the sons of the house of Pasteur fighting against his elder brother"... But Charles Chamberland is also running. "I hope you will come to an agreement: it is impossible for you to run against each other and, as your candidacy has already been put forward and accepted by many, it seems to me that it would have been better to stick to it. I don't know why Chamberland is running. [...] You can be sure, of course, that you will never be treated as an enemy by the Pasteur Institute: I don't know that you have anything but sympathies there"... Chamberland's candidacy is a maneuver by Laveran, Vallin and a few others... Calmette is flattered to be invited to present his "modest work" at the Internat conference, and will present "the current state of the question of vaccines from the special point of view that concerns general pathology"... He defends Paul Ehrlich and his work on the development of a treatment for syphilis, after the "polemics published by certain French newspapers concerning one of his discoveries which best honors humanity. Those of us who know the greatness of Ehrlich's work, the extent of his unselfishness, are left aching. Metchnikoff said this to you yesterday with his customary ardor, which should not offend you, for he holds you, your person and your talent as a writer in the highest esteem"... The last letter is addressed to Mme de Fleury after Maurice's death.
