Poe was not happy with Griswold’s review of his poetry. Things got even more tense when Poe resigned from Graham's Magazine, only to be replaced by Griswold. Poe eventually died, but even then Griswold didn't have nice things to say about him in the obituary. Griswold wrote that Poe’s death "will startle many, but few will be grieved by it." Ouch!

But how did the feud start? Well, Faulkner once said that Hemingway "has never been known to use a word that might send a reader to the dictionary." To which Hemingway responded, "Poor Faulkner. Does he really think big emotions come from big words?"
