Envelope from Germany to Thames Photographic Co. with Photochemie logo

A letter sent from Germany to a British company named The Thames Photographic Co. Unfortunately, no definitive information is available about this company. However, it is believed that it might have been among the photographic material manufacturers or suppliers in England. On the back of the envelope, the logo "Photochemie Berlin N113" can be seen.

Photochemie was a publisher with its own photographic printing plant, and it mainly produced postcards using gravure printing. Starting from 1907, the company used its triangular logo on postcards featuring various models such as children, women, and couples. Between 1914 and 1919, the company also produced an extensive series of German film stars. However, in these series, the company name was used instead of the triangular logo.

Unger & Hoffmann: From Paper to Magic Lanterns & Cameras

Unger & Hoffmann was established in 1878 as a company primarily engaged in paper manufacturing, reflecting the strong industrial base of the late nineteenth century. During the following decades, the firm adapted to the rapidly evolving visual and technical landscape by expanding its activities beyond paper production. By the 1890s, it had entered the field of photographic and optical equipment, producing cameras and magic lantern devices, which were widely used for visual presentations and educational purposes.

As photography became more widespread, the company further diversified its production to include photographic paper and glass plates, essential materials for image creation and reproduction at the time. In addition, Unger & Hoffmann contributed to the dissemination of visual culture by publishing slide series designed for use with magic lanterns, thereby participating in both the technical and educational dimensions of early image projection.

A significant transition occurred in 1926, when the production of photographic plates and paper was transferred to the Mimosa company. This shift reflects broader structural changes within the photographic industry, where specialization and consolidation became increasingly common as technologies advanced and markets evolved.

Overall, the history of Unger & Hoffmann illustrates the transformation of a traditional manufacturing enterprise into a participant in the expanding photographic industry, highlighting the close relationship between material production, visual technology, and the circulation of images in the late nineteenth and early twentieth centuries.
