In the 1940s master architect Le Corbusier developed the Modulor, a universal system of proportion based on the measurements of the human body and the golden section found throughout nature. The Modulor Rule, a two-sided measuring tape housed in a distinctive tin container, features the renowned system in striking red and blue with inch and centimeter scales on the reverse. The package also includes an insert with a brief duallanguage introduction (in English and French). The Modulor Rule is a perfect gift for architects and modern design buffs alike—an essential tool and important piece of design history, now accessible to all.
