Swiss-born Charles-Édouard Jeanneret, best known by his adopted name Le Corbusier, was a highly influential architect, designer, painter, urban planner and writer whose career spanned almost five decades. A pioneer of progress-minded modern architecture, Le Corbusier sought to impose a rational order on the chaos of the world through design. He rejected the excessive architectural ornament and developed a style that became known as Brutalism, creating buildings with elemental geometric forms that were made of industrial materials such as steel and reinforced concrete. Le Corbusier believed that pure, well-designed spaces could offer a lesson in how little is needed to achieve happiness. To convey this notion, the architect prioritized modern, open interiors and emphasized light, rational designs. His architecture and interiors share a clear sense of space and structural order, underlining the beauty in harmony, proportion and simplicity.
