(Paris, Crochard, 1820). No wrappers as extracted fron 'Annales de Chimie et de Physique', Volume 15 (2e Series). Pp. 93-102. First appearance of this importent paper in which Arago gives an account of his discovery of how iron and steel could be magnetized by the action of the voltaic current, THE FIRST STEP TOWARDS THE ELECTRIC TELEGRAPH. "Arago . made several important contributions to electromagnetism on his own. On 20 September 1820 he announced the discovery of the temporary magnetization of soft iron by an electric current, which suggested to Ampère a theory about the nature of magnetic "currents" and provided the technological key to the electric telegraph. Ampère calculated that the magnetic power could be multiplied by twisting the current-carrying wire into a helix, and with Arago he carried out the first experiments on primitive solenoids. In his historical articles Arago was always careful to credit Ampère with the major share of this discovery, which ultimately depended upon Ampère?s mathematical theory."(DSB).Arago formed a close freinship with Fresnel,whose views on the nature of light he ardently supported. He assisted Fresnel in some of his most importent work and made original discoveries in the same field.Magie "A Source Book in Physics", p. 443 ff.…

First printing of probably the first (in the Juillet issue of Annales) official announcement of Daguerre's invention of the photographic process. The paper offered here preceeded the official report in Comptes Rendues which was published at the end of 1839 (in the July-December issue). The first report of on the discovery was presented to the Royal Academy on January 7, 1839 and delivered in full on August 19, 1839 (and printed in the July-Dec. issue of Comptes Rendues). The paper also preceeded Daguerre's own publication of 1839 "Historique et description du daguerréotypie."In 1839 Arago took a personal interest in announcing and popularizing the inventions of Niepce and Daguerre, who were awarded government pensions as a result of Arago?s recognition of their inventions? potential significance."In 1829 Daguerre went into partnership with Niepce, who had managed to produce images by the action of light some three years earlier but had failed to make the process really practical. Daguerre carried on and began to use copper plates on which silver salts were deposited. ight was made to focus upon that and an image was formed. The light portions of the image darkened the salts, while the shadowy portions left them unaffected. The unchanged salt was dissolved away by sodium thiosulfate (a process that had been suggested by John Herschel and a permanent image of sorts was left behind."(Asimov).…

First Edition of the official and complete report of the invention of the "daguerreotype", the photographic process invented by Louis Daguerre. Together with the preliminary report of the invention (OF JANUARY 7). The presentation by Arago preceeded Daguerre's own publication "Historique de description des procédés du daguerreotype et du diorama", (1839). "When the attempt to exploit the process of daguerreotype was unsuccessfull, Daguerre and Nièpce decided to offer their method to the government. Daguerre approached Francois Jean Arago, to whom he imparted, under the seal of secrecy his processes and those of Nicéphore Niépce. It was fortunate that Arago possessed such a great insight into the invention, which he received enthusiastically. He reported the invention of the daguerretype to the Academy of Sciences on January 7, 1839. The secrecy, however, was not observed very carefully, for the "Gazette de France" published a note abouit it on January 6, 1839, although without printing any details."(Eder "History of Photography"). …

Gay-Lussac et Arago", Tome I, IV, IX, X, XI, XV, XVII, XX, XXI, XXIII, XXVIII and XXIX. Some memoirs with scattered brownspots. All but volume 15 with the orig. titlepages to the volumes. Vol. XV having instead of the titlepage, a sample of the orig. printed wrappers, December issue 1820. Bound at end of volume 2. The memoir, no. 25a below is inserted at the end of volume 2. Some of the memoirs having textillustrations. Some versos of titlepages with stamps. First appearances of this groundbreaking series of papers and memoirs in which Fresnel established the scientific basis for the wave theory of light and gave the theoretical framework for explaining, in the context of his theory of the transversal nature of lightwaves, the phenomena of double refraction, refraction, dispersion, polarization, interference, diffraction patterns, diffraction fringes as light spreads around objects, etc. He developed mathematically the hypothesis of the wave nature of light and he demonstrates its conformity with experience. His study of light was a dynamic interplay between theory and observation, between mathematics and experiment. - The offered series also comprises the contributions from Arago and the rapports from The French Academy's committees by Ampère, Biot and Fourier - see below nos. 6,11,14,15,a.nd 18."From the point of view of method, his investigations extended from the manual operations of the laboratory to the most abstract mathematical analyses. Few physicists since Newton had been so versatile."(Silliman in "Historical Studies in the Physical Sciences", vol. 4, p. 155.)."The wave-thory at this time was still encumbered with difficulties. Diffraction was not satisfactorily explained" for polarization no explanation of any kind was forthcoming the Huygenian construction appeared to require two different luminiferous media within double refracting bodies and the universality of that construction had been impugned by Brewster's discovery of biaxial crystals. The upholders of the emission theory, emboldened by the success of Laplace's theory of double refraction, thought the time ripe for their final triunph and as a step to this, in March 1817 they proposed Diffration as the subject of the Academy's prize for 1818. Their expectation was disappointed" and the successful memoir afforded the first of a series of reverses of which, in the short space of seven years, the corpuscular theory was completely owerthrown. The author was Augustin Fresnel."(Whittaker "A History of the Theories of Aether & Electricity", vol. 1, p.107 ff.)."This concept of transverse waves met with the greatest hostility from the scientists of the day, who could not imagine an extremely fluid and rarified ether which at the same time possessed the mechanical properties of a rigid body. Even Arago admitted that he could not follow the exuberant engineer in his ideas. ButFresnel was convinced that at last he had the key to many mysteries, and with his model of waves he gave a full clarification of the phenomena of polarization. With insuperable precision he explained a long series of extremely complicated experiments, such as those of chromatic polarization that Arago himself had discovered by chance in 1811, and which the followers of Newton could not explain in spite of all their efforts. Following this line Fresnel reached the synthesis which is his masterpiece.we must recall the final interpretation that he gave of the famous phenomenon of partial reflection by transparent surfaces, that simple phenomenon which until then had puzzled Grimaldi, Newton, and Huygens, and which in Malus's experiments had unexpectedly acquired a special importencee as it had been compared to the great mystery of double refraction."(Ronchi "The Nature of Light", p. 255 ff.).Comprising:1.
