This post begins: Edmond Hamilton created the “Hugh Davidson” pseudonym for “Vampire Village” (Weird Tales, November 1932). I’m not sure why since he has no other story under his own name in the issue, the usual reason Pulp writers used nom de plums. Another common reason is they don’t want their name associated with a “shocking” element that might sully their name. “Vampire Village” doesn’t have any such element. (Did Ed consider writing pure horror a way to sully his name in the Science Fiction market? I doubt it, since he was one of the stars of a horror magazine.)
