A thorough compilation of Walt Whitmans best poetry prose and short tales Walt Whitman was a little-known Long Island journalist and poet who self-published Leaves of Grass in 1855. It had only twelve poems and was a tiny volume. Whitman spent his entire life revising and expanding the work in order to give a new voice to the nation that had been shaken by the Civil War but his initial act of bravado in responding to Ralph Waldo Emersons call for a national poet has cemented Whitmans status as the archetypal American author.
