Uncredited, Chapman wrote the first two Torch stories in the Fifties revival, in Young Men 24 (Dec/53) and 25 (Feb/54).
Art on the YM 24 story is by Russ Heath, with the exception of a splash panel pasteover of the Torch by Carl Burgos.
The first clue to Chapman's writing a story is "Ow-w-w"—most often hyphenated exactly like that, but not always. That's best as an indication when the other writers at the particular company and time aren't using it, of course. And "Holy Smokes" in the splash panel helps lead me to Chapman here. The following panels are from a story with Chapman's credit line, "My Brother . . . the Ghoul" in Adventures into Weird Worlds 6 (May/52), with art by George Roussos.
Another occasional clue to Chapman is seen by comparing the first page of Young Men 25's Torch story with the first page of "My Brother . . . the Ghoul" (and note "Holy Smokes" again in the Torch splash).
The tier of panels before the splash in each case is something Chapman uses off and on; also, for that matter, the splash with a single story panel following, as in YM 24.
Other writers did the rest of the superhero stories in Atlas's short-lived revival experiment of the mid-Fifties.
