Early modernist Architects discarded the decorative styles of the 19th century and sougth to merge architecture with industry. The result was a simple, logical functional building style, as much industrial as artistic.
The first curtain wall was introduced and designed by the founder of the International Style in Architecture, Architect Walter Gropius. He is a German Architect who was invited to teach at art school in germany called Bauhaus, "Building House". When in Bauhaus moved from Weimar to Dessau in 1926, Gropius constructed the new campus according to his philosophy of clean, functional, modern design. Gropius's most important contribution was the so called "Curtain Wall", the exterior wall of glass that also displays the building's interior design.
