Thompson wrote under the pen name "C. Hall Thompson" from his teen years and throughout his career.
He lived in Philadelphia throughout his life. He had four works published in Weird Tales:
- "The Spawn of the Green Abyss" (Nov. 1946)
- "The Will of Claude Ashur" (July 1947)
- "The Pale Criminal" (Sept. 1947)
- "Clay" (May 1948)
The Derleth Controversy
There is an anecdotal story, somewhat well attested, that Thompson was told to cease and desist writing Mythos stories by August Derleth who was acting in a proprietary manner with respect to Lovecraft's works.
In the estimation of some, C. Hall Thompson has become a kind of ingroup / outgroup cause celebre, exemplifying the nature of what became a clique around August Derleth for the decades 1950 to circa 1970.
The contrary view is basically that as literary executor and "custodian" of Lovecraft's oeuvre, Derleth put Lovecraft in the public eye and behaved appropriately by as it were "policing" those who were "allowed" to write Mythos works.
