Denny O'Neil
Denny O'Neil was a Bronze Age writer best known for redefining Batman, writing the socially conscious Green Lantern/Green Arrow run with Neal Adams, and contributing to Iron Man and The Question. His name is closely tied to the early Bronze Age shift toward more grounded superhero storytelling, and his Batman work serves as a reference point for collectors focused on key character developments, first appearances, and creator-driven runs.
