Art Deco was a major design force that flourished between the two World Wars. It evolved from earlier artistic movements, and developed in direct response to the revolutionary changes in scientific, social and political events of the early 20th century and was generally referred to as Art Moderne. it was inspired by both the 1922 discovery of King Tut's tomb, and the fascination it generated with ancient cultures, as well as the machine age. Also known as Style Moderne, Art Deco was a popular international design movement from 1925 until 1939 (and some push it back to the 1900's) which affected architecture, home design, furniture, decorative accessories, fashion, fashion accessories, visual arts, etc. It's influence peaked in Europe in the roaring '20's but continued strongly in the United States during the 1930's. At the time, this style was seen as elegant, functional, and ultra modern. Various French artists formed a formal collective known as, La Société des artistes décorateurs (the society of the decorator artists). Founders included Hector Guimard, Eugène Grasset, Raoul Lachenal, Paul Follot, Maurice Dufrene, and Emile Decour. They organized the 1925 Exposition Internationale des Arts Décoratifs et Industriels Modernes (International Exposition of Modern Industrial and Decorative Art), which would feature French art and business interests. The term Art Deco was derived from the Exposition of 1925, though it was not until the late 1960s that this term was coined by art historian Bevis Hillier, and popularized by his 1968 book Art Deco of the 20s and 30s. This movement was, in a sense, an amalgam of many different styles and movements of the early 20th century, including Constructivism, Cubism, Modernism, Bauhaus, Art Nouveau, and Futurism. The structure of art deco is based on mathematical geometric shapes. Some fractionated, crystalline, faceted forms of decorative Cubism and Futurism. characterized by use of materials such as aluminium, stainless steel, lacquer, inlaid wood, sharkskin (shagreen), and zebraskin. The bold use of stepped forms and sweeping curves (unlike the sinuous, natural curves of the Art Nouveau), chevron patterns, and the sunburst motif are typical of Art Deco. A parallel movement called Streamline Moderne, or simply Streamline, followed close behind. Streamline was influenced by the modern aerodynamic designs emerging from advancing technologies in aviation, ballistics, and other fields requiring high velocity. The attractive shapes resulting from scientifically applied aerodynamic principles were enthusiastically adopted within Art Deco, applying streamlining techniques to other useful objects in everyday life. Art Deco slowly lost patronage in the West after reaching mass production, when it began to be derided as gaudy and presenting a false image of luxury. Eventually, the style was cut short by the austerities of World War II.
During the Depression, very few buildings (especially houses) were constructed. One exception was New York City where rectangular skyscrapers next to narrow sidewalks were being built, the result of which was that very little light was reaching the pedestrian sidewalks. Thus, in 1924, a "setback" ordinance was passed: upper stories of a tall building were stepped back from the lower stories to allow more light to reach the street. Art Deco buildings in other cities imitated the setback feature to the extent that it became a common feature for Art Deco buildings.
The largest concentration of Art Deco buildings is in New York City (skyscrapers) and Miami (apartment houses and hotels).
Common Art Deco features:
Setbacks (steplike recessions in a wall) emphasizing the geometric form
Geometric ornament: parallel straight lines, zig-zags, chevrons, lozenges (diamondlike shape, but not a square)
Stylized (abstracted) floral motifs
Stylized figure sculpture
Octagonal lamps, clocks
Sunrise and floral patterns in ornamentation
Intense colors in terra cotta, glass, colored glazed bricks, mosaic tiles, and colored mirrors
Hard-edged low relief ornamentation around door and window openings, e.g. stepped frontispiece and stepped window head
Volutes in door surrounds
Strips of windows with decorated iron grille work in surrounds to add vertical feeling
Metal windows: sash, casement
Although straight-headed windows are more popular, an occasional circular window or rounded window and door jamb is found
Buildings are" stripped down" to their purest forms
