Achille-Isidore Gilbert (French, 1828–1899) was a French painter and lithographer known for his detailed depictions of public life, architecture, and grand events. Active during the Second Empire and early Third Republic, he brought a theatrical eye to urban scenes - balancing precision with flair. Whether capturing firework displays, city squares, or ceremonial architecture, Gilbert rendered spectacle with a draftsman’s discipline and a showman’s sense of scale.
