Yeah, the Haney comparison fits. And either one of them might be considered Ernest Hemingway, relative to Silver Age DC standards.
A 13-year-old Jim Shooter set the world on fire in 1966 with his writing on Legion in ADVENTURE COMICS 346-380, simply taking notes on the storytelling techniques used at Marvel, and submitting them to use on a series for DC. In that era, he also worked on ACTION and SUPERMAN for editor Mort Weisinger.
It still amazes me that a 13 year old kid could enter comics and write professionally with more engaging stories than the DC pros at that time. But such was the standard of comics writing in that era.
When DC's editors found out Shooter was under 18, they took away his books and said he could come back when he was an adult. Which Shooter later did from 1974-1976, but by then Mort Weisinger had retired, and Shooter found it far more difficult to work for Julius Schwartz and Murray Boltinoff, at which point he defected over to Marvel.
