Jack Kirby is one of the most influential and popular artists in comics history. With Stan Lee, he created the Fantastic Four and defined the drawing and narrative style of Marvel Comics from the 1960s to the present day. Kirby's distinctive narrative drawing, use of bold abstraction, and creation of angst-ridden and morally flawed heroes mark him as one of the most influential mainstream creators in comics. Charles Hatfield analyzes the development of Kirby's cartooning technique, his use of dynamic composition, the recurring themes and moral ambiguities in his work, his eventual split from Lee, and his later work as a solo artist.
