William Wordsworth (April 7, 1770 - April 23, 1850) was a major English romantic poet who, with Samuel Taylor Coleridge, helped launch the Romantic Age in English literature with their 1798 joint publication, Lyrical Ballads . Wordsworth's masterpiece is generally considered to be The Prelude , an autobiographical poem of his early years that was revised and expanded a number of times. It was never published during his lifetime, and was only given the title after his death. Up until this time it was generally known as the poem "to Coleridge". Wordsworth was England's Poet Laureate from 1843 until his death in 1850.
