Anatomical Illustrations

"Jan Ladmiral (1698 - 1773) was a pupil and assistant to the great anatomical illustrator Jacob Christoph Le Blon (1670 - 1741). Afterward, Ladmiral, apparently, presumed ownership of Le Blon's secret invention for coloring mezzotint engravings, a process using three different impressions of primary colors (blue, yellow, and red) for one image and thus able to produce different color values without the use of black."
