Barnett Newman was an influential American artist known for his contributions to the abstract expressionist movement. Born in 1905, he became famous for his large-scale paintings that often featured bold colors and simple forms. His work emphasized the emotional experience of art, focusing on the viewer's interaction with the canvas. Newman is best known for his use of "zips," which are vertical lines that divide fields of color in his paintings. This technique aimed to create a sense of depth and movement, inviting viewers to engage with the artwork on a deeper level. His legacy continues to impact contemporary art and artists today.
