Philip Wylie

From Wikipedia:

Gladiator (1930) partially inspired the comic-book character Superman.[citation needed]
The Savage Gentleman (1932) “Pulp historians point out that the themes of The Savage Gentleman are replicated to an uncanny degree in the pulp character Clark “Doc” Savage (1933) created by Lester Dent…” – Richard A. Lupoff
When Worlds Collide (1933), co-written with Edwin Balmer, inspired Alex Raymond’s comic strip Flash Gordon and as adapted as an eponymous 1951 film by producer George Pal.

His nonfiction book of essays, Generation of Vipers (1942), was a best-seller during the 1940s and inspired the term “Momism”.
