Holograms existed in the nineteenth century, though they were not so called and were not very exciting or newsworthy. Going back even farther into the seventeenth and eighteenth centuries we find the diffraction of light being studied with keen interest by Grimaldi, Newton, Hooke, Delisle, Young, Fresnel and numerous others. All could have had holograms if they had had photography. All looked at the diffraction patterns but had no method of recording them except by drawings.
