Henri Le Sidaner, an often overlooked French post-impressionist painter, is enjoying something of a revival with four retrospective exhibitions in northern France - his main stomping ground when he was producing his most collectable work.
His great-grandson Yann Farinaux Le Sidaner curated the exhibitions. He explained to BBC News how they have contributed to his current resurgence.
