Boris Lacroix is a French architect and interior designer famous for his fundamental contribution to the Art Déco and for the creations, in particular the lamps, of the Fifties. Artistic director of the fashion house Vionnet from the mid-twenties until the end of the thirties, he was one of the pioneers of modern lighting, developing the use of acrylic and geometric design. Natural son of Jeanne Aumont-Lacroix and the Russian Grand Duke Boris Vladimirovich, he entered the world of design in 1920, working in the laboratory of Paul Dumas in Paris. In the following years he was trained as an architect and designer and began working as a draftsman for the designer Madeline Vionnet, whose fashion house will become artistic director in 1925. In 1927 Lacroix exhibited his projects at the Salon des Artistes Décorateurs and at the Salon d’Automne with great critical acclaim. Particularly appreciated are the use and skill in the processing of materials such as glass and metal. Having left Vionnet in 1937, he devoted himself exclusively to his own activity as a designer, who in 1950 saw the turning point in his career. That year, in fact, Lacroix launched the Dog Lamp, achieving a huge success, followed by others, such as the popular table lamp “Lamp 315”.
