William Erwin "Will" Eisner (March 6, 1917 – January 3, 2005) was an American cartoonist, writer, and entrepreneur. He was one of the earliest cartoonists to work in the American comic book industry, and his series The Spirit (1940–1952) was noted for its experiments in content and form. In 1978, he popularized the term "graphic novel" with the publication of his book A Contract with God. He was an early contributor to formal comics studies with his book Comics and Sequential Art (1985).
