Stan Lee (born Stanley Martin Lieber December 28, 1922) was an American comic book writer, editor, publisher, and producer. He rose through the ranks of a family-run business called Timely Publications which would later become Marvel Comics. He was the primary creative leader for two decades, leading its expansion from a small division of a publishing house to a multimedia corporation that dominated the comics and film industries.

In collaboration with others at Marvel—particularly co-writers/artists Jack Kirby and Steve Ditko—he co-created iconic characters, including superheroes Spider-Man, the X-Men, Iron Man, Thor, the Hulk, Ant-Man, the Wasp, the Fantastic Four, Black Panther, Daredevil, Doctor Strange, Scarlet Witch, and Black Widow. These and other characters' introductions in the 1960s pioneered a more naturalistic approach in superhero comics, and in the 1970s Lee challenged the restrictions of the Comics Code Authority, indirectly leading to changes in its policies.
