A large manufacturer of motion picture film stocks and chemicals, videotapes, still photographic film, papers and chemicals, and photographic accessories. Many films in archives will have been printed on Kodak stock and will bear Kodak Year Symbols.
With the invention and development of motion pictures in the late eighteen hundreds there came the need for long lengths of flexible transparent film support which could be coated with photographic emulsion to provide positive and negative film. As a result of close cooperation between George Eastman and Thomas A Edison, a film support made from cellulose nitrate was developed. A Kodak chemist, Harry M. Reichenbach, formulated the first successful base coating composition in 1889.
