Jack Kirby is widely regarded as the foundational visual architect of American superhero comics. Co-creator of Captain America with Joe Simon, and the driving force alongside Stan Lee of the Marvel Age — including Fantastic Four, Thor, The X-Men, The Avengers, The Hulk and Black Panther — he later redefined DC Comics with his Fourth World saga. Known simply as “The King”, Kirby’s dynamic, kinetic style and boundless visual imagination underpin the vocabulary of modern mainstream comics.
