Stam, generally less well-known than deserved, was one of the most significant European artists and designers of the 1920’s and 30’s. He was the first to come up with a tubular steel chair (winning a case against Breuer to establish this). Mies selected him to feature in a famous showcase of modernist architecture. Gropius wanted him to lead the Bauhaus’s architecture department (he declined). He worked briefly with Poelzig. Lissitzky was a close friend, and like Rietveld and to some extent Corbusier, Giedion and van Eesteren, a collaborator and colleague in the pursuit of advanced ideas about architecture and planning.
