In 1922 Bernard-Albin GRAS designed a series of lamps for use in offices and in industrial environments. The Gras lamp , as it was called, was astounding in its simple, robust and ergonomic design. There are neither screws nor welded joints in the basic form. In 1927 the Ravel company purchased the patent and started production of the GRAS lamps.
Bernard- Albin Gras was one of the most innovative designers of the 20th century. The functional aesthetic of his lamps and man design details were truly original and far ahead of their time. Early on Le Corbusier was seduced by the modern design and user-friendliness of the lamps and became one of Lampe Gras's most enthusiastic supporters, using the lamps in his own offices as well as employing them in numerous architectural projects all over the world. Well-know artists as Sonia Delaunay and Georges Braque also used these lamps in their studios. For the first time in history, a lamp was equally popular in professional as well as in residential applications.
