National Comics Publications in the context of "Jack Kirby"

Jack Kirby (/ˈkɜːrbi/; born Jacob Kurtzberg; August 28, 1917 – February 6, 1994) was an American comic book artist, widely regarded as one of the medium's major innovators and one of its most prolific and influential creators. He grew up in New York City and learned to draw cartoon figures by tracing characters from comic strips and editorial cartoons. He entered the nascent comics industry in the 1930s, drawing various comics features under different pen names, including Jack Curtiss, before settling on Jack Kirby. In 1940, he and writer-editor Joe Simon created the highly successful superhero character Captain America for Timely Comics, predecessor of Marvel Comics. During the 1940s, Kirby regularly teamed with Simon, creating numerous characters for that company and for National Comics Publications, later to become DC Comics.

After serving in the European Theater in World War II, Kirby produced work for DC Comics, Harvey Comics, Hillman Periodicals and other publishers. At Crestwood Publications, he and Simon created the genre of romance comics and later founded their own short-lived comic company, Mainline Publications. Kirby was involved in Timely's 1950s iteration, Atlas Comics, which in the next decade became Marvel. There, in the 1960s, Kirby co-created many of the company's major characters, including Ant-Man, the Avengers, the Black Panther, the Fantastic Four, the Hulk, Iron Man, the Silver Surfer, Thor, and the X-Men, among many others. Kirby's titles garnered high sales and critical acclaim, but in 1970, feeling he had been treated unfairly, largely in the realm of authorship credit and creators' rights, Kirby left the company for rival DC.
