The classic era of mid-century modern design spanned from the 1930's to the 1960's. It began with the Bauhaus movement in Germany. Other Western European designers began furthering the modernist movement and adding their own influences, such as France's le Corbusier incorporating tubular steel into his furniture pieces. Other non-traditional furniture materials from this era included acrylic, glass, chrome, stainless steel and plywood. The mid-century modern style then received it's biggest and most influential addition from the Scandinavians, primarily from the Danes and Finns. Renowned designers such as Eero Saarinen, Eero Aarnio, Alvar Aalto, Hans Wegner and Arne Jacobsen quickly became international household names, as well their iconic furniture... the Tulip, Wishbone, Ball, Egg, Womb, Bubble, Spider, etc. Soon after, inspired by their overseas counterparts, American modernist designers such as Charles and Ray Eames, George Nelson and Issamu Noguchi began creating their own famous furniture pieces.
