Inside the Vault

Arnold Genthe was the first to photograph Morgan’s study in color, using a new technology invented by the French brothers Lumière. The completed glass plates, called autochromes, could be viewed with a hinged stand called a diascope, which incorporated a mirror that reflected the color image. Morgan was so pleased with Genthe’s work that he ordered multiple diascopes mounted into fine leather cases. Genthe later recalled the unusual circumstances of the shoot:

During the long exposure of the plates I was permitted to go into the vault where the rare and precious manuscripts were kept and to study those in which I was particularly interested. This of itself would have been ample compensation to me.
