Born in 1819, Walt Whitman was a legendary American poet who spoke his mind. In 1855, he self-published his collection Leaves of Grass; the book is now a landmark in American literature. Continuing to produce new editions of Leaves of Grass along with original works, Whitman passed away in 1892. After his death, he was buried in a tomb he designed and had built on a lot in Harleigh Cemetery. Along with Emily Dickinson, he is considered one of America's most important poets.
