This is the portrait of Gustave Revol, the eldest son of Joseph-Marie. Like his father and grandfather before him, he is a figure of local authority, both economically and politically. The archives indicate that he was amiable and kind. He left his mark on the company in a long-standing manner: when he died in 1861, his son chose to honour him by renaming the factory after him: Gustave Revol, Father and Son.
