William Blake was born in London in 1757. He was apprenticed to a master engraver and then studied at the Royal Academy under the guidance of Joshua Reynolds. In 1789 he engraved and published Songs of Innocence and the contrasting Songs of Experience came later in 1794. A poet, painter and printmaker of great originality and imagination, his work was largely unrecognized during his lifetime and he struggled to make a living. Blake is now considered a seminal figure in the history of both the poetry and visual arts of the Romantic Age. He died in 1827.

Walt Whitman (1819-1892) was a celebrated American poet, chiefly known for his controversial and highly original poetry collection Leaves of Grass. Born in 1819 on Long Island, he worked as a journalist, teacher, government clerk, and volunteer nurse during the Civil War.

Whitman published his seminal work in 1855 with his own money, soon becoming one of the world's most popular and influential poets. After suffering a stroke in 1873 he retired to Camden, New Jersey, where he died nineteen years later - just two months after the final edition of Leaves of Grass appeared on sale.
