You appear to me not to be aware that in April 1853 I [illegible deletion] sent a memoir <3> to the French Academy of Sciences<4> (which is found in the Comptes Rendus <5>) on the
production subject of raised photographic pictures obtained formed upon spaces coated with a mixture of gelatine and Bichromate of Potash and specifically in which memoir I specifically pointed out that the great beauty of these pictures arose from their not being not flat like other photographs, but raised above the surface level in some parts, and depressed in others thereby producing a new and pleasing effect. And I took casts in fusible metal of such surfaces - The principal part of your invention was therefore anticipated by me in 1852 or 1853 -
I do not mention this with any view to depreciate your ingenious experiments but merely to establish my own rights in the matter as an inventor, and as I am desirous of proceeding in the most amicable manner towards the gentlemen who are associated with you in this Company, I will further say, additionally, that if you will furnish me with the name of the Solicitor of the Company <6> I will call upon that gentleman on my return to Town, and have a conversation with him.
on this subject By this means My Dear Sir, we shall avoid all misunderstanding on the subject. Before I conclude, I will advert to another point, which is not strictly speaking

2. The Patent Photo-Galvanographic Company (commonly, The Photogalvanographic Company) was based on the work of Paul Pretsch (1808-1873), Austrian photographer & inventor and former Manager of the Imperial Printing Establishment in Vienna. Based in Holloway Road, Islington, London, from 1856-1857, Pretsch took over as manager and Roger Fenton (1819-1869), photographer & lawyer, was a partner and their chief photographer. Starting in late 1856, they published a serial portfolio, Photographic Art Treasures, or Nature and Art Illustrated by Art and Nature, illustratated with photogalvanographs derived from several photographer's works. Photogalvanography was uncomfortably closely based on elements of WHFT's patented 1852 Photographic Engraving but, unlike Talbot, the plates were heavily retouched by hand. Compounding the legal objections of Talbot, their former manager, Duncan Campbell Dallas, set up a competing company to produce the Dallastype. The company collapsed and near the end of 1860 Pretsch, out of money, allowed his patent to lapse. A public appeal was launched in 1861 to assist him but he returned to Vienna in 1863 in ill health, going back to the Imperial Printing Establishment, but finally succumbing to cholera. See Doc. No: 07253; Doc. No: 07660; Doc. No: 07465.
