William Cullen Bryant was an American romantic poet, journalist, and long-time editor of the New York Evening Post. Although "Thanatopsis", his most famous poem, has been said to date from 1811, it is much more probable that Bryant began its composition in 1813, or even later. What is known about its publication is that his father took some pages of verse from his son's desk and submitted them, along with his own work, to the North American Review in 1817. The Review was edited by Edward Tyrrel Channing at the time and, upon receiving it, read the poem to his assistant, who immediately exclaimed, "That was never written on this side of the water!" Someone at the North American joined two of the son's discrete fragments, gave the result the Greek-derived title Thanatopsis (meditation on death), mistakenly attributed it to the father, and published it. It was well-received, and soon Bryant was publishing poems with some regularity, including "To a Waterfowl" in 1821.


On January 11, 1821, Bryant, still striving to build a legal career, married Frances Fairchild. Soon after, having received an invitation to address the Harvard University Phi Beta Kappa Society at the school's August commencement, Bryant spent months working on "The Ages," a panorama in verse of the history of civilization, culminating in the establishment of the United States. That poem led a collection, entitled Poems, which he arranged to publish on the same trip to Cambridge. For that book, he added sets of lines at the beginning and end of "Thanatopsis." His career as a poet was launched. Even so, it was not until 1832, when an expanded Poems was published in the U.S. and, with the assistance of Washington Irving, in Britain, that he won recognition as America's leading poet.


His poetry has been described as being "of a thoughtful, meditative character, and makes but slight appeal to the mass of readers."
