Walt Whitman (1819–1892) was an American poet, and essayist, part of the transition between transcendentalism and realism. His work was very controversial, particularly his poetry collection Leaves of Grass, which he would continue editing and revising until his death, described in his time as obscene. Whitman was deeply influenced by deism and he denied any one faith was more important than another, and embraced all religions equally. Rufus Wilmot Griswold suggested Whitman was guilty of "that horrible sin not to be mentioned among Christians". Beyond this, he was hailed as America's first "poet of democracy". This collection, contains his complete works, in their original editions: Leaves of Grass, Drum-Taps, Good-Bye My Fancy, Specimen Days, Collect, November Boughs, Memoranda, The Wound Dresser; poetry, essays & letters.
