Paul Chadwick (1902–1972) was a pulp magazine author who wrote many stories under his own name and various pseudonyms.
As was the case with many prolific contributors to the pulps, he wrote in a number of different genres including detective stories, science fiction and westerns.
He created Secret Agent X, published under the "house name" of Brant House, and also wrote the one and only issue of the Doc Savage clone Captain Hazzard (May 1938) under the name of Chester Hawks.
The Hammond stories were notable in combining three emerging genres of the time: science fiction and weird menace as well as hardboiled detectives.
