Some argue that he was ahead of his time. It is certainly the case that he was a one-off.

'Leaves of Grass', which was first published as a handful of poems and grew to more than 400, is a loosely-connected collection. It focuses on the body and the material world and celebrates the natural world. The poems do not rhyme and do not follow any accepted rules.

Walt Whitman (1819-1892) was an American poet, essayist and journalist. He was a humanist and is often called the father of free verse - a sobriquet inspired by the unstructured nature of much of his poetry.

Whitman worked in hospitals caring for the wounded during the American Civil War.
