From the onset of her career, Charlotte Perriand was a maverick who believed in good design as a force for the betterment of society. Many young designers would be devastated by a rejection from Le Corbusier’s studio, but when the great architect told her they had no use for a female furniture designer, Perriand only became more determined to prove her mettle as an artist. Under Le Corbusier, and long after she left his studio, Perriand’s contributions to both furniture design and architecture demonstrated a unique attention to the organic artistry of nature as well as the egalitarian possibilities of the machine age. Her leftwing populist politics motivated much of her work, from modular furniture systems to major architectural projects. This monograph explores Perriand’s most famous interiors, original furniture and architectural projects, as well as her never-before-seen sketchbooks, shedding new light on her creative process and place in design history.
