Stella Paul - A new avanguard emerged in the early 1940s, primarily in New York, where a small group of loosely affiliated artists created a stylistically diverse body of work that introduced radical new directions in art—and shifted the art world's focus. Never a formal association, the artists known as "Abstract Expressionists" or "The New York School" did, however, share some common assumptions. Among others, artists such as Jackson Pollock (1912–1956), Willem de Kooning (1904–1997), Franz Kline (1910–1962), Lee Krasner (1908–1984), Robert Motherwell (1915–1991), William Baziotes (1912–1963), Mark Rothko (1903–1970), Barnett Newman (1905–1970), Adolph Gottlieb (1903–1974), Richard Pousette-Dart (1916–1992), and Clyfford Still (1904–1980) advanced audacious formal inventions in a search for significant content. Breaking away from accepted conventions in both technique and subject matter, the artists made monumentally scaled works that stood as reflections of their individual psyches—and in doing so, attempted to tap into universal inner sources. These artists valued spontaneity and improvisation, and they accorded the highest importance to process. Their work resists stylistic categorization, but it can be clustered around two basic inclinations: an emphasis on dynamic, energetic gesture, in contrast to a reflective, cerebral focus on more open fields of color. In either case, the imagery was primarily abstract. Even when depicting images based on visual realities, the Abstract Expressionists favored a highly abstracted mode.
Action Painting In 1947, Pollock developed a radical new technique, pouring and dripping thinned paint onto raw canvas laid on the ground (instead of traditional methods of painting in which pigment is applied by brush to primed, stretched canvas positioned on an easel). The paintings were entirely nonobjective. In their subject matter (or seeming lack of one), scale (huge), and technique (no brush, no stretcher bars, no easel), the works were shocking to many viewers. De Kooning, too, was developing his own version of a highly charged, gestural style, alternating between abstract work and powerful iconic figurative images. Other colleagues, including Krasner and Kline, were equally engaged in creating an art of dynamic gesture in which every inch of a picture is fully charged. For Abstract Expressionists, the authenticity or value of a work lay in its directness and immediacy of expression. A painting is meant to be a revelation of the artist's authentic identity. The gesture, the artist's "signature," is evidence of the actual process of the work's creation. It is in reference to this aspect of the work that critic Harold Rosenberg coined the term "action painting" in 1952: "At a certain moment the canvas began to appear to one American painter after another as an arena in which to act—rather than as a space in which to reproduce, re-design, analyze, or 'express' an object, actual or imagined. What was to go on the canvas was not a picture but an event."
Another path lay in the expressive potential of color and was called “Color Field” . Rothko, Newman, and Still, for instance, created art based on simplified, large-format, color-dominated fields.
The first generation of Abstract Expressionism flourished between 1943 and the mid-'50s. The movement effectively shifted the art world's focus from Europe (specifically Paris) to New York in the postwar years. The paintings were seen widely in traveling exhibitions and through publications. In the wake of Abstract Expressionism, new generations of artists—both American and European—were profoundly marked by the breakthroughs made by the first generation, and went on to create their own important expressions based on, but not imitative of, those who forged the way.
