Charles Amand-Durand was a French printmaker and publisher. He is best remembered as the pioneer of the héliogravure (aka photogravure) technique. Together with Georges Duplessis, he produced portfolios replicating the work of Old Master printmakers, including Durer, Rembrandt, Claude and Lucas van Leyden. In order to create his prints, a high quality photograph would have been taken of the original print, after which the negative would have been exposed onto a gelatin-covered copper plate and etched with acid. Amand-Durand etched parts of the plate himself and printed his works by hand. While difficult to discern from the original prints, Amand-Durand’s works can be identified by the red stamp of his monogram on the verso of his prints.
