Overview:
• Design By Ludwig Mies van der Rohe and Lilly Reich
• Authentic chairs have a facsimile of Mies van der Rohe's signature on its frame.
• It remains one of the most recognizable early 20th century chairs and will remain a design icon.
History:
Originally only two Barcelona chairs were made for the German Pavilion, which was set at the 1927 International Exposition. Spanish Royals Alfonso XIII and Victoria Eugenie of Battenberg were to preside at the cermony and the chair Mies Van Der Rohe was to design would be used to literally seat royalty. Mies has been quoted about the chair "The government was to receive a king. . . . The chair had to be . . . monumental. In those circumstances, you just couldn't use a kitchen chair." So the form that was decided upon became throne-like, modeled after the sella curulis, an ancient stool used by Roman magistrates.
After the exposition the design became so popular that it was put into production, it has been manufactured almost continuously since 1929

Materials + Manufacturing:
Created before the advent of stainless steel ground welding (Invented at the end of the 1800s, Patented in 1913), the frame was designed to be bolted together. Mies redesigned this component it in 1950, allowing the frame to be a seamless piece of metal. Ivory colored pigskin was used on the original Barcelona Chairs but has since been replaced by high quality leather.
