CURIE, Marie Sklodowska (1867-1934); Pierre CURIE (1859-1906); Gustave BMONT. "Sur une nouvelle substance fortement radio-active, contenue dans la pechblende". - Eugne DEMARAY. "Sur le spectre d'une substance radio-active". In: Comptes rendus hebdomadaires des sances de l'Acadmie des Sciences (127, no. 26), 26 December 1898, pp. 1215-1217 and 1218. Paris: Gauthier-Villars, 1898.
4o (286 x 227 mm). Original mottled boards, printed paper spine label, unopened (minor wear with some chips to extremities).
FIRST EDITION, JOURNAL ISSUE. THE ANNOUNCEMENT OF THE DISCOVERY OF RADIUM. Becquerel's discovery of the radioactive properties of uranium inspired Marie Curie to investigate the phenomenon of radiation. She first proceeded to determine whether there existed any other elements capable of emitting radiation. Having found only one other such element, thorium, among the then known elements, "Marie and her husband Pierre proceeded to search for unknown elements with radioactive properties. In 1898 they discovered two new radioctive elements, polonium and radium; both of these elements are present in pitchblende (uranium ore), but in such minute quantities that the Curies were unable to isolate either one, and had to rely on spectroscopic evidence to prove their existence. Marie Curie's work attracted the attention of Becquerel, who became the intermediary through whom the Curies' papers reached the Academy of Sciences" (Grolier Medicine). On April 12, 1898, Marie had presented a preliminary note to the Academy, and on 18 July, 1898 she and Pierre published their first joint report, "Sur une substance nouvelle radioactive contenue dams la pechblende," in which they announced the discovery of polonium. The present paper, their third report to the Acadmie, signed also by Pierre's assistant G. Bmont, announced their discovery of radium, a far more radioactive element than uranium or thorium. The Curies owed their successes to an extremely sensitive electroscopic apparatus constructed by Pierre and his brother Jacques, which made possible a "new method of chemical analysis based on the precise measurement of radiation emitted, a method still in use" (DSB). The existence of radium--and the validity of the Curies' technique of analysis--was immediately confirmed by the spectroscopist Eugne Demaray, whose report follows the Curies'. After unstinting labors, in 1902 Marie Curie finally succeeded in isolating from several tons of pitchblende a single decigram of radium chloride. RARE. Garrison-Morton-Norman 2003; Grolier Medicine 84B; Norman 545; see PMM 394 note.
