Walt Whitman was a poet during the 1800's, who later in America's modern times became popular for his unique style of poetry. Whitman thought that poetry should be spoken in the "language of ordinary men." His use of the vernacular and vocabulary was unusual and unique for poets of his time period. His poems were most often times about nature and humanity. His poems also helped shed light on America's issues as it began to grow as a country. Sadly Walt Whitman wasn't given full credit for his unique and influential style of writing until after he had passed away.
