To celebrate the first anniversary of our US Materials Catalog, this week ArchDaily is presenting a three-part series on "Material Masters," showing how certain materials have helped to inspire some of the world's greatest architects.

Mies van der Rohe, famous for his saying “less is more,” was one of the preeminent modernist architects, well known for pioneering the extensive use of glass in buildings. His works introduced a new level of simplicity and transparency, and his buildings were often referred to as "skin-and-bones" architecture for their emphasis on steel structure and glass enclosure. In addition to Mies van der Rohe, glass was a major influence for many architects of the modernist movement and reshaped the way we think about and define space. Today, glass has become one of the most used building materials, but its early architectural expression is perhaps best exemplified in the works of Mies.
