Geneviève Dangles (born in 1929) and Christian Defrance (born in 1930) were leading figures in post-war French design. Both graduates of the École Nationale Supérieure des Arts Décoratifs, they established their design studio in 1953 and quickly gained recognition for their clean, modernist aesthetic that helped define mid-century French furniture. Their innovative approach is best represented through their collaboration with the French furniture company Burov, which resulted in iconic pieces such as the “Saturne” armchair (model 44, 1957) and the “Corbeille” armchair (model 58, 1958). Their designs featured elegant metal structures, ergonomic forms, and the use of contemporary materials like lacquered steel, fiberglass, and foam. As active members of the Groupe 4, alongside other major designers like Alain Richard and Joseph-André Motte, they contributed to the modernization of French interiors in both private and corporate settings. Their work, blending form and function, is now celebrated in 20th-century design galleries and continues to attract interest from collectors and design historians alike.
