Roy Lichtenstein was one of the first American Pop artists. After studying at Ohio State University and getting a degree in fine arts Lichtenstein began teaching at Rutgers University. Influenced by another professor at Rutgers, Allan Kaprow, Lichtenstein created his first pop paintings using cartoon imagery techniques derived from the appearance of commercial printing. During this time period Lichtenstein developed his unique comic book style, often using Ben-Day dots and thick outlines.
During the 1960s, his paintings were exhibited at the Leo Castelli Gallery in New York City and, along with Andy Warhol, Jasper Johns, James Rosenquist, and others. One of his most famous images is Whaam! (1963), which is displayed in London at Tate Modern. Whamm! is one of the earliest known examples of pop-art; Lichtenstein adapted a comic-book panel from a 1962 issue of DC Comics' All American Men of War. The painting depicts a fighter aircraft firing a rocket into an enemy plane, with a red-and-yellow explosion.
Later in Lichtenstein’s career he began reproducing masterpieces such as Matisse and Picasso. Lichtenstein’s series titled, Artist’s Studio, is seen as a personal tribute to Matisse, particularly his two paintings Red Studio and Pink Studio.
