Organic abstraction is abstract art built from rounded, wavy forms modeled on what one finds in nature - shells and honeycombs, bones and musculature, the curves of growth and flow. It emerged in the 1920s and 1930s, partly under the influence of Henri Bergson's celebration of intuition and natural process, and grew as a humane counterweight to the geometric rigor of Cubism and Constructivism. As the utopian hopes of those movements faded in the 1930s, sculptors such as Jean Arp, Constantin Brâncuși, Barbara Hepworth, and Henry Moore turned from rational construction to emulating nature's generative forces. Mid-century design and architecture absorbed the same vocabulary: Isamu Noguchi's furniture, Eero Saarinen's Tulip chair, and Frank Lloyd Wright's Guggenheim Museum, whose coiled plan has been likened to a chambered nautilus. Some critics now group the tendency under the broader label biomorphic abstraction.
To me, the Guggenheim Art Museum in New York City is one of the most eccentric, but still old school architectural delights -- on the insideCC BY-SA 4.0 (credit: Ron Sterling) · source
Defining characteristics
Rounded, wavy, flowing abstract forms without hard edges
Shapes distilled from natural structures: shells, bones, pebbles, cells, growths
Smooth, continuous surfaces emphasizing volume and contour
Biomorphic asymmetry suggesting living organisms without depicting them
Warm, humanistic feel pitched against geometric abstraction
