Becquerel’s notes and scientific diagrams on Radioactivity

BECQUEREL HENRI: (1852-1908) French physicist, the first person to discover evidence of radioactivity. Nobel Prize winner for Physics, 1903. A good set of manuscript notes, scientific calculations and diagrams prepared by Becquerel, unsigned, two pages, oblong 4to, n.p., n.d., in French. The notes, presumably prepared by the physicist for a lecture, are headed Radioactivity, and form an extensive list of prompts, in part, 'Historical. 1st Observation 1896. 1st proof. Medal. Discharge of electrified bodies. Experiment on phosphorescent sulphides. General for uranium salts. Atomic property. Role of the air. Laws of loss. Exp. by Kelvin, Beattie and de Smolan, 1897. Rutherford 1899. Ionization. Saturation current, 1898. Thorium. M. Schmidt and M. Curie. Work of M. and Mme. Curie. Polonium. Radium. Debierne. Actinium. Radium spectrum. Magnetic deviation experiences. Giesel, Meyer and Schveider. H. B. Cliches. Concentration. Deviable and non-deviable rays'. To the foot of the first page appear various scientific calculations and in the left column of each page Becquerel has added eleven small pen sketches illustrating the deviations of Polonium. An interesting and rare scientific manuscript on the subject for which Becquerel is most famous, and in which he acknowledges the contributions made by his colleagues including Pierre and Marie Curie, Ernest Rutherford etc. VG
