William Wordsworth (1770-1850) 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. Samuel Taylor Coleridge (1772-1834) was an English poet, critic, and philosopher one of the Lake Poets. He is probably best known for his poems The Rime of the Ancient Mariner and Kubla Khan, as well as his major prose work Biographia Literaria. Coleridge was critical of the literary taste of his contemporaries, and a literary conservative insofar as he was afraid that the lack of taste in the ever growing masses of literate people would mean a continued desecration of literature itself.
