Streamline Moderne, sometimes termed Art Moderne, is a late type of the Art Deco architecture and design that emerged in the 1930s. Its architectural style emphasized curving forms, long horizontal lines, and sometimes nautical elements.Moderne architecture includes other subtypes besides Art Moderne / Streamline, it must be noted, such as PWA Moderne.
The first streamline buildings evolved from the work of New Objectivity artists, a movement connected to the German Werkbund, that was initiated by Hermann Muthesius (see e.g. Mossehaus).
The oldest surviving example of Streamline design in the United States is the 1929 Lake Worth Playhouse, in Lake Worth, Florida.
As the Great Depression of the 1930s progressed, Americans saw a new aspect of Art Deco—i.e., streamlining, a concept first conceived by industrial designers who stripped Art Deco design of its ornament in favor of the aerodynamic pure-line concept of motion and speed developed from scientific thinking. Cylindrical forms and long horizontal windowing also may be influenced by constructivism. As a result, an array of designers quickly ultra-modernized and streamlined the designs of everyday objects. Manufacturers of clocks, radios, telephones, cars, furniture, and many other household appliances embraced the concept.
The style was the first to incorporate electric light into architectural structure. In the first-class dining room of the SS Normandie, fitted out 1933–35, twelve tall pillars of Lalique glass, and 38 columns lit from within illuminated the room. The Strand Palace Hotel foyer (1930), preserved from demolition by the Victoria and Albert Museum during 1969, was one of the first uses of internally lit architectural glass, and coincidentally was the first Moderne interior preserved in a museum.
