This week marks the centennial of Jack “King” Kirby, arguably the most important contributor to the art form of comics of all-time. Kirby, born Jacob Kurtzberg (the son of Jewish immigrants; you know the drill), is mostly known for his iconic artwork for Marvel Comics. Working with the likes of Jewish writers Joe Simon and Stan Lee, Kirby co-created the X-Men, the Fantastic Four, and Captain America, just to name a few that have had staying power. But some of Kirby's most fascinating, innovative work is (comparatively) less-well known, coming after he switched to Marvel's competitor, DC, and began to write as well as draw, now in more direct control over his creations.
