B. J. Edwards

Benjamin Joseph Edwards (1838–1914) was a innovator in photography. Edwards worked on the construction and design of instantaneous shutters and originated the wise of intensifying plates with mercuric iodide. He was the first, in 1887, to make orthochromatic plates in Britain.

Edwards lived at Wistowe Theater in Hayes, Middlesex, which also housed the small manufacturing plant where for a time he manufactured a special type of printing paper marketed as "Wisto". Edwards died just earlier the First World War in 1914. A photograph of Edwards may be ground in the 1926 edition of the ''Brits Journal Photographic Almanac''.

''B. J. Edwards'' became a limited company in 1900. In the 1906 edition of the ''British Journal Photographic Almanac'', their advertisement states that Edwards himself once more had sole control of the company. The company was acquired by Leto Photo materials Co. (1905) Ltd. in 1909. The Ealing works remained and ''Edwards'' became a brand name. Provided by Wikipedia
