An 1854 catalogue mentions a Richard Griffin & Co. of Glasgow. The Playfair Collection catalogue states that the brothers Richard Thomas and John Joseph Griffin set up as dealers and manufacturers of chemical apparatus in Glasgow. This may have been as early as 1826 and was certainly before 1837 for which date there is an apparatus catalogue. The London branch was started around 1848.

Charles Griffin was running the firm in 1885 when was discharged from bankruptcy. John Ross Griffin (d.1921), grandson of John Joseph G., worked at the firm at some point. For a short time, c.1890 - c.1892, Richard C. Murray managed the photographic side of Griffin. A.W. Green ran the photographic side from 1911 taking over from a Mr. Ibetson.

Griffin's involvement in photographic supplies expanded in the late 1890s and early 1900s. They were distributors for Velox paper and still manufactured albumen paper. Griffin took over the sensitised paper business of J.D. Mucklow in 1900.
