Le Corbusier, Pierre Jeanneret, and Charlotte Perriand were pioneering figures of modernist design whose collaboration produced some of the most iconic furniture of the 20th century. The three first came together in the late 1920s and worked closely until the Second World War disbanded the group, creating a legacy of pieces that continue to define minimalist, functional living today. Their shared vision centered on clean lines, architectural clarity, and a belief that better design helps create a better society, blending industrial materials like tubular steel with timeless form and functional living spaces. Charlotte Perriand, one of the few women to shape modern design during a male-dominated era, brought her expertise as an architect and interior designer to the collaboration, while Le Corbusier's architectural philosophy and Pierre Jeanneret's precision engineering complemented her work. Their close relationship led to simple, functional products designed for apartments and everyday life, with pieces characterized by simplicity, functionality, and enduring style that remain influential in contemporary design. Their collaborative work includes celebrated furniture pieces such as the iconic tubular steel chairs and the LC4 chaise longue, now produced by Cassina and furnishing private residences and hospitality spaces worldwide. Their designs embody the modernist ethos of form following function while maintaining an aesthetic elegance that transcends their era.
