Couppier dedicó (dedicatoria impresa) esta obra a Niepce de Saint-Victor con estas palabras: "Monsieur, le petit ouvrage que je livre au public traite d'une partie de la Photographie dont vous êtes le créateur. J'ai été déterminé à l'entreprendre par vos encouragements, et j'ai, pendant que je l'ècrivais, été souvent dirigé par vos conseils bienveillants. Permettez-moi donc dew remplir, en vous lñe dédiant, un devoir de justice et de reconnaissance [...]". Jules Couppier was French photographer who made glass stereoviews in the mid-nineteenth century. His inventory of views included major sites in France, Algeria, Belgium, Italy, and Russia. He also followed the French army to northern Italy in 1859 to photograph the Franco-Austrian War, where he made the first known photograph of soldiers killed in battle. "Jules Couppier, a chemist, was a founding member of the Sociéte Française de Photographie (1854) an outgrowth of the first photographic society in the world, Sociéte Héliographique, founded in 1851. In 1848, Abel Niépce de Saint-Victor, the second cousin of the first photographer, J. N. Niépce, and a founder of the Sociéte Héliographique, published a paper in the journal of the Academy of Sciences on his experiments with albumen coated glass plates for obtaining a negative from which a sharper and tonally richer positive print could be obtained. A distinct advantage of this process was that it allowed for the manufacture of the plates in advance of their use; however, the plate had a low sensitivity to light, therefore portraiture was not possible. In this, one of the earliest full manuals covering the albumen negative on glass and positive print processes, Couppier has dedicated it appropriately to Niépce de Saint-Victor. As a skilled chemist, Couppier was able to improve upon many of the earlier difficulties of sensitivity that had limited this process; improved formulas are provided. Couppier is known today for his albumen glass plate stereographs; one from 1859 taken in the cemetery of Melegnano, showing the bodies of over 2000 combatants, is a harsh testament to the brutality of war" (Andrew Cahan).
