Just in time for the release of Kill Your Darlings, a movie starring Daniel Radcliffe as Allen Ginsberg, Slate asks, “Who really said you should ‘kill your darlings’?”
The answer: not Ginsberg or William Faulkner, both of whom the quote is often attributed to, but rather Arthur Quiller-Couch, a writer and academic in England in the early 1900s.
Evidently, Quiller-Couch considered the vast majority of letters to be murderable darlings; he published his work under the pen name “Q.”
