Jackson Pollock is known for his unique style of abstract expressionism in painting, characterized by his drip technique. This method involved laying a canvas on the ground and dripping or pouring paint from above, allowing for spontaneous movement and rhythm. Pollock's work epitomizes the post-World War II American art scene, breaking away from traditional forms and emphasizing the act of painting itself. His innovative style has had a lasting impact on contemporary art, inspiring movements focused on process, gesture, and emotional expression.
