[CHEMISTRY - PHYSICS]. SEGUIN, Jean-Marie (1823-1911), French physicist. Correspondence composed of 12 autograph letters signed, addressed to the Nancy chemist Jérôme Nicklès (1820-1869). Nancy (1), Grenoble (9) and s.l.n.d. (2), 15 January 1855 - 22 November 1865. ). 37 pp. in-8.
Interesting set of friendly and professional letters, composed of a formal application of Seguin to join the Academy of Nancy, then of letters with a warmer tone, sent at the time of his departure from Nancy to Grenoble. "I have the honor of expressing to you my desire to be included among the candidates for one of the places soon to be vacant in the Academy of Stanislas and I beg you to present my candidacy for the approval of the Company. He evokes his thesis in chemistry and his thesis in physics (indices of refraction of dissolutions and work on accidental colors), their colleagues, their works, etc. "I do not intend to remain without relation with Nancy; and you know that I counted on your friendship to link, between us, the chemistry of the North and the physics of the South". He mentions the rector of the faculty of Nancy, Hervé Faye, asks for advice on the organization of conferences, congratulates his friend for his decoration as knight of the Legion of Honor (1862), mentions a ministerial gift to the faculty of Grenoble: "three of the new devices of acoustics of Rudolph Koenig", etc. Nicklès asked for a bottle of clear water that Seguin fetched from the Isère upstream from Grenoble: "I evaporated 18 liters of it in a porcelain capsule [...] the residue is stronger than that of spring or well water [...] and after having removed the carbonates by acetic acid, there still remains a little sand or insoluble clay [...]".
Nicklès devoted a large part of his research to fluorine and its compounds (analysis of mineral and spring waters - action of hydrofluoric acid on glass, a technique that will be used by glass artists such as Emile Gallé, etc.). His correspondence of about 1,000 letters (with many chemists: on fermentation (Louis Pasteur and Justus von Liebig), on the history of chemistry (Hermann Kopp and Marcelin Berthelot) is in the Special Collections Research Center of Temple University in Pennsylvania.
