For other uses, see Leaves of Grass (disambiguation). Leaves of Grass is a poetry collection by the American poet Walt Whitman (1819â1892). Though the first edition was published in 1855, Whitman spent most of his professional life writing and re-writing Leaves of Grass, revising it multiple times until his death. This resulted in vastly different editions over four decadesâthe first a small book of twelve poems and the last a compilation of over 400.
Whitman wrote in the preface to the 1855 edition of Leaves of Grass, The proof of a poet is that his country absorbs him as affectionately as he has absorbed it.. He believed there was a vital, symbiotic relationship between the poet and society.arly in his career, he also produced a temperance novel, Franklin Evans (1842). Whitman's major work, Leaves of Grass, was first published in 1855 with his own money. The work was an attempt at reaching out to the common person with an American epic. He continued expanding and revising it until his death in 1892.
