Griswold began soliciting contributions for the annual in 1843, initially intending to call it The Christian Offering. It was first edited by Nathaniel Parker Willis, John Keese and finally by Sarah Josepha Hale. ^{[3] [4]} It was in the 1844 issue that Edgar Allan Poe first published "Morning on the Wissahiccon". ^[5] Other contributors included Henry Wadsworth Longfellow, Elizabeth F.
