In 1945, we see traces of a similar human-centered approach in architecture that we have seen in psychology with Rogerian psychology. The Swiss and French architect Le Corbusier wanted to find a measurement system for architecture that could be universal and based on humans.

The measurement system aims to create architectural elements, like buildings and furniture, that offer maximal comfort to the humans who use them. The Modulor is based on the Golden Ratio that can be found in nature in almost everything from the human body to leaves or shells.

The Modulor was in the creation process between 1940 and 1950. It seems that the official date that historians keep for the creation of the Modulor is 1945. The book that theorized this system was published in 1950 and was titled “Le Modulor: essai sur une mesure harmonique à l’échelle humaine applicable universellement à l’architecture et à la mécanique”.

This article is part of the book "A Tiny History of Service Design, " a tiny two-hour read that goes through the historical events that created what Service Design is today.
