Jack King Kirby s comics career began in 1937 and continued for nearly six decades. With partner Joe Simon, Kirby first made his mark in comics in the 1940s by drawing and/or creating numerous features for DC Comics including Sandman, The Newsboy Legion and Manhunter, and for Marvel including Captain America, The Young Allies and the Kid Commandos. As the most valued team in comics, Simon and Kirby went on to create titles and concepts including Fighting American, Boy s Ranch and the creation of the romance comics genre. In 1961, the first issue of Marvel s Fantastic Four cemented Kirby s reputation as comics preeminent creator, and a slew of famous titles followed that elevated him to legendary status, including The Incredible Hulk, Avengers and X-Men. Kirby returned to DC in 1971 with his classic Fourth World Trilogy, which was followed by The Demon and Kamandi. Kirby continued working and innovating in comics until his death in 1994.
