Although she is often considered one of the 20th century's most renowned women in architecture, Charlotte Perriand (1903 -1999) was not an architect- she regarded herself as an interior designer and took issue with those who thought her merely a furruture designer. Her best-known interior was a temporary installation that she and Pierre Jeanneret completed while in the atelier of Le Cor busier for the 1929 Paris Salon d'Automne exhibition. In that same year, in collaboration with Le Corbusier and Jeanneret, she designed three chairs: the chaise-longue, grand confort, and fauteuil a dossier basculant. All were essential "equipment" in the 1930s architecture of Le Cor busier, and all are in production today.
