Fizeau, Armand Hippolyte Louis. “Ueber die zur Erzeugung der Moser’schen Bilder-beitragenden Ursachen”, which is the first German edition of “Sur les causes qui concouraent a la production des images de Moser” from the Comptes Rendus de l’Academie des Sciences 1842, volume 15. In Annalen der Physik, volume 58, 1843, No. 4, part VII, pp 592-593 in the issue of pp (521)-668 (with one folding plate). This issue is removed from a larger bound volume, with no outer wrappers. Very Good. Other works include those of C.F. Naumann, G.B. Airy, Faraday, Arago, and a longer piece by Daguerre. (“Ueber ein neues Versahren, die zu photographischen Bildern bestimmten Platten zu poliren, welches, so lange di eSufsern Umstande gleich bleiben, einerlei Resultate gicht”, pp 586-592, translated from the Comptes Rendus de l’Academie des Sciences volume 16, p. 588.)

• “On 19 August 1839 Arago made public a description of a new process of “light painting” or heliography that had been invented by L.-J.-M. Daguerre. The daguerrotype, as the result of this process soon came to be called, was a crude forerunner of the modern photograph. Fitzeau’s earliest work in science was an attempt to improve Daguerre’s process and to make the heliograph an instrument of science. He showed that by covering the surface of the developed plate with a salt of gold, oxidation of the surface chemicals could be prevented and the contrasts between light and dark could be considerably heightened. He is often credited with the first use of bromine vapors to hasten the development of the photographic image, but this seems uncertain. Fizeau also introduced a widely used but unpatented method for turning a photograph into a photoetching.”–Dictionary of Scientific Biography

• “From 1844 Fizeau and Foucault undertook a series of precise and mechanically ingenious optical experiments that would ultimately have a profound effect on the course of physics. By the middle of the nineteenth century, most scientists had come to accept the wave theory of light, formulated near the beginning of the century by Thomas Young and Augustin Fresnel. There remained, however, several gaps in the investigation of the experimental consequences of the theory. For example, in the study of interference fringes produced by two rays of light issuing from the same source, only several dozen fringes on each side of the central band had been observed.”–Dictionary of Scientific Biography
