Designed in 1921, Bernard-Albin GRAS developed a line of office and industrial lamps. The «GRAS» lamp, as it was subsequently called, was astounding in its simple, robust and yet very ergonomic design. There are neither screws nor welded joints in the basic form. RAVEL obtained the patent in 1927 and began manufacturing the “GRAS” lamps. Among the most innovative designers of the 20th century was Bernard-Albin GRAS. In particular, the design of the arms, stems, brackets, and bases were truly original and far ahead of their time, a true sign of his originality. As early as 1925, Le Corbusier was captivated by the design and user-friendliness of GRAS lamps. He used them in his own office and in a number of his architectural projects around the world. As well as Robert Mallet-Stevens, Emile Jacques Ruhlmann and Eileen Gray, these artists also followed a similar trend. The lamps were also used in the studios of well-known artists like Sonia Delaunay and Georges Braque. Lamps became equally popular in both professional and residential applications for the first time in history. Throughout the world, the ‘GRAS’ lamp has become one of the most sought-after collectibles, especially in France, the USA, and Japan. Bernard-Albin Gras’ visionary and talented design has stood the test of time.
