Editor of DC Comics who led the revival of the classic superheroes like The Flash and Green Lantern.
He joined DC Comics at a time when the popularity of many of its superheroes declined and their stories mothballed in favor of Westerns and animal stories.
His first project at D.C. Comics was revamping The Flash with a more modern scarlet costume, and it turned the once-moribund superhero into an instant success.
He was born in the Bronx, New York and had grown up reading the Amazing Stories science fiction magazine.
He was among the most well-known science-fiction literary agents, representing future great authors like Ray Bradbury.
