The Patent Photo-galvano-graphic Company, <1>
Holloway Place, Holloway Road,
9th June 1856H. F. Talbot Esq.
I remain with every sentiment of respect Dear Sir yours faithfully
H. Fox Talbot Esq.
1. A company formed by Pretch, Roger Fenton (1819–1869), photographer & lawyer and others, that took over Pretch’s patent for a photographic engraving process. It produced heavily retouched reproductions of photographs. WHFT considered that the patent infringed Part 1 of his own [see Doc. No: 07253] insofar as the first part of Pretsch’s process too used the combination of gelatine and potassium bichromate. Pretsch’s second part involved electrotyping – i.e. ‘galvanography’ – whereas WHFT’s used etching. WHFT began legal action [see Doc. No: 07660] but dropped it when the company failed and fell apart [see Doc. No: 07465].
3. Not traced.
