Mart Stam was a Dutch architect, urban planner and chair designer. Stam's career intersects with important moments in the history of 20th century European architecture, including chair design at the Bauhaus. After moving to Berlin, Stam devised a steel-tubing cantilever chair using lengths of standard gas pipe and standard pipe joint fittings. Ludwig Mies van der Rohe became aware of Stam's work on the chair and mentioned it to Marcel Breuer at the Bauhaus. This led almost immediately to variations on the cantilevered tubular-steel chair theme by both Mies and Breuer, and began an entire genre in chair design.
