In 1922, Le Corbusier began working in the new rue de Sèvres, Paris, atelier with his cousin Pierre Jeanneret with whom he shared research projects and shared life-long professional relationship.  In October 1927, the pair decided to draw on the contribution of a young architect who had already begun to establish a reputation on the architectural scene of the time: Charlotte Perriand. Their collaboration lasted through to 1937 and was extremely fruitful, especially in the field of furniture design. Thanks to Cassina’s ongoing production, there is continued interest in the conceptual contents of their work and the level of quality attained.
