Which architect/designer from the 20th century created a system of proportions using a human figure with one raised arm?

Le Corbusier, a prominent architect and designer from the 20th century, developed a system known as the "Modulor," which is based on human proportions and is intended to create harmony in architectural design. This system incorporates a representation of a human figure with one arm raised, which allows for the design of spaces and elements that are more comfortable and accessible for human use. The Modulor reflects his belief in the importance of human scale in architecture and has influenced modern architectural practices. This proportional system serves as a guideline for dimensions in buildings, ensuring that spaces resonate with the human experience through a scaled and aesthetically pleasing framework.

The other individuals mentioned, while influential in their own rights, did not specifically create a proportional system that is centered on a human figure with a raised arm, making Le Corbusier's contribution unique and significant in the context of 20th-century design principles.
