Edgar Allan Poe, whose poetry had been included in Griswold's anthology, published a critical response that questioned which poets were included. This began a rivalry which grew when Griswold succeeded Poe as editor of "Graham's Magazine" at a salary higher than Poe's. Later, the two competed for the attention of poet Frances Sargent Osgood. They never reconciled their differences, and after Poe's mysterious death in 1849, Griswold wrote an unsympathetic obituary. Claiming to be Poe's chosen literary executor, he began a campaign to harm Poe's reputation that lasted until his own death eight years later.
