Tony Selmersheim (1871–1971) was a major French decorator and designer at the turn of the 20th century, and a central figure in the renewal of the decorative arts in France. The son of architect Paul Selmersheim, he grew up in an artistic environment that naturally led him to pursue a career in the arts. He trained at the École nationale supérieure des arts décoratifs and later under Eugène Grasset at the École Guérin, developing an early interest in mechanized production. In 1895, he presented a library design intended for mechanical fabrication—an innovative concept for the time.

That same year, he co-founded the Société des Cinq with Félix Aubert, Alexandre Charpentier, Jean Dampt, and Étienne Moreau-Nélaton, aiming to integrate industrial techniques into decorative design. The collective quickly evolved into L’Art dans Tout, an influential group advocating for a synthesis of art, craftsmanship, and industry.

Among his students was Jacques Adnet, who would later become a leading figure in French modern design. Selmersheim also contributed to prestigious projects, notably the decoration of the Villa Demoiselle in Reims, a landmark of the Art Nouveau movement. A visionary and innovator, Tony Selmersheim left a lasting impact on the development of French furniture and the decorative arts throughout the 20th century.
