J. H. Dallmeyer was a British company, founded in 1860. Their main business was to manufacture lenses, but they also sold cameras. Some of these were manufactured by Dallmeyer themselves, some were made elsewhere then equipped with Dallmeyer lenses and sold under that name.
Dallmeyer was born in Prussia. On coming to London, he worked for optician Andrew Ross, and later married Ross' daughter. Dallmeyer went into business for himself after Ross' death in 1859; Ross' son Thomas continued the Ross business. Dallmeyer designed both photographic lenses and telescopes, and was on the council of both the Royal Photographic and Astronomical Societies. He passed on the business to his son, Thomas R. Dallmeyer before his death late in 1883.
