Le Corbusier, a Swiss-French architect, is known for pioneering modern architecture and introducing the 'five points of architecture' which emphasized functionality, efficiency, and harmony with nature. His concept of the 'radiant city' aimed to create utopian urban environments with segregation of zones and high-rise buildings, influencing modern urban planning despite the idea not being fully realized. Throughout his career, he impacted architecture with innovative materials, versatile projects, and iconic furniture designs, leaving a complex legacy that continues to inspire discussions on architecture and human well-being.
