The Gentleman’s Magazine, July 1862, presents “Engraving by Photography,’ an article relating to the development of photogalvongraphy. The article reads… we can present our readers with some specimens of a process which appears to be an extraordinary achievement, and of which the consequences may be of great importance. The illustration has been taken from nature by Mr. Francis Bedford, and the engraved block, absolutely untouched by the graver, produced by Paul Pretsch, produced by engraved printing blocks (surface copper, backed with type metal, mounted on wood, like the cast of a wood engraving) to be printed by the ordinary printing press with or without type … Photographs in our time are still perishable, but in printer’s-ink and paper stand the test of centuries.
