First appearance of pioneer-paper in astronomical photography, where he took wet-plate photographs of the moon-blocked sun during a total solar eclipse, and from them discovered solar prominences. - This was the first solar eclipse to be photographed, using the Kew Photoheliograph, a purpose-built combined camera and telescope designed by de la Rue and built in 1857 by Andrew Ross. De la Rue, Warren 1815-89, British scientist and inventor. Especially noted as an astronomer, he was a pioneer in celestial photography. He adapted the wet-plate process to lunar photography and invented (1858) for Kew Observatory a photoheliograph, the first device to give good solar pictures. His photographs of a solar eclipse in 1860 demonstrated that prominences observed at the sun's edge are of solar origin. De la Rue is known also for his research in chemistry, solar physics, and electrical discharge through gases.In 1860 De la Rue took the photoheliograph to Spain for the purpose of photographing the total solar eclipse which occurred on 18 July of that year. This expedition formed the subject of the Bakerian Lecture - the paper offered -. The photographs obtained on that occasion proved beyond doubt the solar character of the prominences or red flames, seen around the limb of the moon during a solar eclipse. In 1873 De la Rue gave up active work in astronomy, and presented most of his astronomical instruments to the university observatory, Oxford. Subsequently, in the year 1887, he provided the same observatory with a 13-inch refractor to enable it to take part in the International Photographic Survey of the Heavens.

First apperance of of the paper in which Janssen announced the first observations of a Solar Prominence without Eclipse. ""Janssen and Sir Norman Lockyer independently and about the same time discovered the method of observing solar prominences and the limb of the sun through using a high dispersion spectroscope in order to project the bright hydrogen lines of the prominence spectrum on the much attenuated background of the solar spectrum."" (Shapley & Howarth ""A Source Book in Astronomy"", where this paper is translated on pp. 308-310).""This (the spectra of helium in the sun) was announced on the same day by the French astronomer Janssen, who was in India observing a total eclipse. As a result, the French government some ten years later struck a medallion showing the heads of both scientists.By that time, the two men had made a much more dramatic discovery at the same time, this time in cooperation. Janssen, studying the spectrum ofthe sun during the eclipse, had noted a fine line he did not recognize. he send a report on this to Lockyer, an acknowledges expert on solar spectra. Lockyer compared the reported position of the line with lines of known elements, concluding that it must belong to a yeat unknown element, possibly not even existing on the earth. He named the element, from the Greek word for the sun.""(Asimov).Parkinson ""Breakthroughs"" 1868 A.

First edition in French of Kirchhoff's milestone papers on the interpretation of the dark D lines - noticed by Fraunhofer in 1814 - in the spectrum of the sun, the papers that inspired Max Planck to his theory of quanta (1900). The papers are the French translations of his papers published in Abhandl. d. königl. Akad. d. Wissenscchaften in Berlin in 1861 and 1862.In the course of his preparatory work in the autumn of 1859, Kirchhoff made an unexpected observation. It had long been known that the dark D lines, noticed in the solar spectrum by Fraunhofer (1814), coincided with the yellow lines emitted by flames containing sodium.....Kirchhoff's unexpected discovery was that if the intensity of the solar spectrum increased above a certain limit, the dark D lines were made much darker by the interrposition of the sodium flame. He instantly felt that he had got hold of ""something fundamental"", even though he was at a loss to suggest an explanation. On the day following the surprising observation, Kirchhoff found the the correct interpretation, which wass soon confirmed by new experiments: a substance capable of emittiing a certain spectral line has a strong absorptive power for the same line....The dark D lines in the solar spectrum could accordingly be ascribed to absorption by a solar atmosphere containing sodium. Immense prospects thus opened up of ascertaining the chemical composition of the sun and other stars from the study of their optical spectra. A few more weeks sufficed for Kirchhoff to elaborate a quantitative theory of the relationship between emissive and absorptive poweer.""(DSB VII, pp. 381-82).PMM, 278 b. - Barchas, 1169-70 - Sparrow, 117 - Horbli, 59 - Dibner, 153 (the note).

First printing of this important paper, which together with Becquerel's paper ""Mémoire sur les effets èlectriques produits sous l'influence des rayons solaires"" and ""Recherches sur les effets de la radiation chimique de la lumière solaire, au moyen des courants électriques"", published the same year, marks the beginning of Solar-Cell-Energy, the first step in a long path to solar panels, and a technology of immense importence for humanity. In 1923 Albert Einstein received the Nobel Prize for his theories explaining the photoelectric effect (his 1905-paper).The ""photovoltaic effect"" is the basic physical process through which a solar cell converts sunlight into electricity. In 1839, nineteen-year-old Edmund Becquerel, a French experimental physicist, discovered the photovoltaic effect while experimenting with an electrolytic cell made up of two metal electrodes. Becquerel found that certain materials would produce small amounts of electric current when exposed to light.
