Jack Katz is an American comic book artist and writer, painter and art teacher known for his graphic novel The First Kingdom, a 24-issue epic he began during the era of underground comix.

A graphic novel is a long-form work of sequential art. The term graphic novel is often applied broadly, including fiction, non-fiction, and anthologized work, though this practice is highly contested by comics scholars and industry professionals. It is, at least in the United States, typically distinct from the term comic book, which is generally used for comics periodicals and trade paperbacks.
