In the late 1970s and early 1980s, two Jewish cartoonists brought the term “graphic novel” to the mainstream. Will Eisner’s A Contract With God tells the story of poor Jewish immigrants in New York tenements while Art Spiegelman’s Maus depicts two storylines that center around the Holocaust. These books address heavy subjects and differ from the lighter fare in comic books, which are usually thinner, magazine-like publications. The term graphic novel has come to refer to non-fiction, not just fiction.
