One of the most frequently used chair in interior design - modernist classic originally designed exclusively for the German Pavilion, Ibero-American Exposition hosted by Barcelona, Spain, in 1929. The design resulted from collaboration between the famous Bauhaus architect Ludwig Mies van der Rohe and his longtime partner and companion, architect and designer Lilly Reich, whose contributions have been acknowledged only recently (it's a men's world). The design of the chair was inspired by ancient folding chairs.
