Neal Adams (June 15, 1941 – April 28, 2022) was an American comic book artist. He was the co-founder of the graphic design studio Continuity Associates, and was a creators-rights advocate who helped secure a pension and recognition for Superman creators Jerry Siegel and Joe Shuster. During his career, Adams co-created the characters Ra's al Ghul, Man-Bat, and John Stewart for DC Comics.
After drawing the comic strip based on the television drama Ben Casey in the early 1960s, Adams was hired as a freelancer by DC Comics in 1967. Later that year, he became the artist for the superhero character Deadman in the science fiction comic book Strange Adventures. Adams and writer Dennis O'Neil collaborated on influential runs on Batman and Green Lantern/Green Arrow in the early 1970s. For Batman, the duo returned the Batman character to his gothic roots as a contrast to the Batman television series of the 1960s. During their Green Lantern/Green Arrow run, O'Neil and Adams introduced a mature, realistic tone through stories such as "Snowbirds Don't Fly", in which Green Arrow's young ward Roy "Speedy" Harper is revealed to have become addicted to drugs. The duo created and introduced the Green Lantern character John Stewart in 1971.
Following his runs on Batman and Green Lantern, Adams drew other books for DC such as Superman vs. Muhammad Ali in 1978. In addition to his work with DC, Adams simultaneously freelanced for Marvel Comics on books such as Uncanny X-Men and The Avengers. In 1971, Adams established the art and illustration studio Continuity Associates with Dick Giordano. In 1984, Adams founded his own comic book company Continuity Comics, which was in business until 1994.
