One of the deans of science fiction, Ray Cummings, appeared not once but twice in the December 1939 issue of MYSTERY TALES.  "I Share My Bride With Satan" appeared under his own name, while "School For Beasts" (where they taught the three "Rs"--rending, ripping and raping) appeared under his Gabriel Wilson pseudonym.  Cummings, whose "girl in the golden atom" idea launched a wave of imitation (much of it penned by himself), was a frequent contributor to the weird menace pulps, beginning in February 1935, when he was published in both HORROR STORIES ("When Ghouls Come Seeking!") and TERROR TALES ("The House of Doomed Brides").  Although he based his penname of Gabriel Wilson on his wife's maiden name, Gabrielle Wilson, there does not appear to be any evidence that these works were done in collaboration with her or were anything other than Cummings' own work.  Another penname of Cummings, Ray King, was also used by him on some of his weird menace work.
