Abel Niepce de Saint-Victor

Claude Félix Abel Niépce de Saint-Victor was a French photographic inventor. Claude was an army lieutenant and the cousin of Nicéphore Niépce. He first experimented in 1847 with negatives made with albumen on glass, a method subsequently used by Frederick Langenheim for his and his brother’s lantern slides. At his laboratory near Paris, Saint-Victor worked on the fixation of natural photographic colour as well as the perfection of his cousin's heliographing process for photomechanical printing. His method of photomechanical printing, called heliogravure, was published in 1856 in Traité pratique de gravure héliographique. In the 1850s, he also published frequently in La Lumière.
