Piron was one of Delacroix’s closest friends from lycée. Although we know relatively little about him, his name is inextricably linked to that of the painter through his unfailing loyalty.
Indeed, Delacroix rewarded this modest postal administrator by making him his heir and one of his executors. Piron not only accomplished this task scrupulously; he also took on the project of publishing a book of souvenirs dedicated to the artist’s friends, using archives he gathered dutifully: Eugène Delacroix, sa vie, son œuvre (1865). The archives of the Musée National Eugène Delacroix have the various documents that belonged to Piron.
