Charlotte Perriand (1903-1999) was a pioneer of modern furniture design. From 1927 – 37, she worked with Le Corbusier and Pierre Jeanneret to develop their systematized furnishings known as "machines for living". Although best remembered for her elegant modernist tubular steel furniture of the 1920's and 1930's, she also produced craft-based designs, such as the Synthese des Arts chair (1955). She is renowned for many interiors such as the Air France offices in London (1957) and Tokyo (1957) and the United Nations conference rooms in Geneva (1960), as well her many collaborations with Jean Prouvé.
