5. He enrolled at Ohio State University in 1940, and studied a wide variety of subjects, including drawing, design, botany, history, and literature. He also took a class with Hoyt L. Sherman, also an artist, whose teachings concerning “organized perception” were highly influential for Lichtenstein.
6. Lichtenstein was drafted into the Army in 1943. Initially, as part of his training, he completed courses in engineering at De Paul University in Chicago, before serving as a clerk and draftsman across Europe.

“I take a cliché and try to organize its forms to make it monumental. The difference is often not great, but it is crucial."

9. He invented a type of rotating easel, so as to be able to paint from different angles. Saying of the mobility this easel offered, Lichtenstein said, “I paint my own pictures upside down or sideways. I often don’t even remember what most of them are about. The subjects aren’t what hold my interest.”
