Jack Kirby (August 28, 1917 – February 6, 1994), born Jacob Kurtzberg, was an American comic book artist, writer and editor regarded by historians and fans as one of the major innovators and most influential creators in the comic book medium.

Growing up poor in New York City, Kurtzberg entered the nascent comics industry in the 1930s. He drew various comics features under different pen names, including Jack Curtiss, ultimately 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, generally teamed with Simon, created numerous characters for that company and for the company that would become DC Comics.

After serving in World War II, Kirby returned to comics and worked in a variety of genres. He contributed to a number of publishers, including DC, Harvey Comics, Hillman Periodicals and Crestwood Publications, where he and Simon created the genre of romance comics. He and Simon also launched their own short-lived comic company, Mainline Publications. Kirby ultimately found himself at Timely's 1950s iteration, Atlas Comics, later to be known as Marvel Comics. There, in the 1960s, he and writer-editor Stan Lee co-created many of Marvel's major characters, including the Fantastic Four, the X-Men, and the Hulk. Despite the high sales and critical acclaim of the Lee-Kirby titles, however, Kirby felt treated unfairly, and left the company in 1970 for rival DC.
