Charlotte Perriand devoted her life to improving the living conditions of as many people as possible, creating an "art of inhabiting" in connection with nature. She used photography not only as a tool for observing reality, but also to promote her conception of a new world. Echoing our current concerns, in the 1930s she used sweeping photomontages to denounce unhealthy urban conditions and present her vision of how life can be made better. Her striking photographic frescoes, including "The Great Misery of Paris" (1936) and the Agriculture Ministry’s waiting room and pavilion at the Exposition Internationale des Arts et Techniques dans la Vie Moderne [International Exposition of Art and Technology in Modern Life] (both 1937), created with Fernand Léger, attest to her modernity. The exhibition offers insights into her idea of the world through her working methods and incredible collection of photographs—period prints, negatives, magazine clippings and personal photographs—on display for the first time, set against recreations of her monumental photomontages.
