Dennis O'Neil

Dennis Joseph O'Neil (May 3, 1939 – June 11, 2020) was an American comic book writer and editor, principally for Marvel Comics and DC Comics from the 1960s through the 1990s, and Group Editor for the Batman family of titles until his retirement. For Batman, the team is credited with returning the character to his dark pulp fiction roots, in contrast to the campy Batman television series of the 1960s. However, comics historian Les Daniels considers O'Neil's "vengeful obsessive-compulsive" Batman to be an original interpretation that has influenced all subsequent portrayals of the character.
