Jack Kirby transformed the language of comics into modern mythology. Born Jacob Kurtzberg in New York, he co-created Captain America, the Fantastic Four, the X-Men, and the New Gods, shaping the visual and narrative grammar of superhero storytelling. His art vibrated with kinetic geometry—figures lunging from cosmic machinery, emotion rendered as architecture. Working across Marvel and DC, Kirby bridged pulp and epic, invention and discipline. His pages taught generations that imagination could have anatomy, that power could be drawn by hand. Few artists expanded popular culture with such conviction or visual music.
