The company was founded by Albert Keller-Dorian (born in 1846 in Mulhouse) in 1923. A specialist in engraving, he relies on the Keller-Dorian process invented by Rodolphe Berthon in 1908 to market color films. Keller-Dorian died shortly after, in 1924. It was taken over by Léon and Charles Silvin. The company went bankrupt in 1930 and became the French Society of Cinematography and Photography via the Célestin group. Rodolphe Berthon decided to dissociate himself from it and founded the Société Française Cinéchromatique in January 1929.
