Marcel Bernheim is listed in 1907 at 25 rue d’Hauteville, Paris, explicitly tied to the G.B. marque and advertising Paris views. A separate listing that same year shows Imprimerie Photo-Mécanique at 154/155 boulevard Magenta under Léon Bernheim. Both disappear from the 1914 directory, suggesting a reshuffle or closure before WWI.
Later, Galerie Marcel Bernheim is documented at 2 bis, rue de Caumartin, Paris (the gallery continued mid-century)
