Samuel Taylor Coleridge ( 21 October 1772 - 25 July 1834) was an English poet, literary critic, philosopher and theologian who, with his friend William Wordsworth, was a founder of the Romantic Movement in England and a member of the Lake Poets. He wrote the poems The Rime of the Ancient Mariner and Kubla Khan, as well as the major prose work Biographia Literaria. His critical work, especially on William Shakespeare, was highly influential, and he helped introduce German idealist philosophy to English-speaking culture. Coleridge coined many familiar words and phrases, including suspension of disbelief. He had a major influence on Ralph Waldo Emerson and on American transcendentalism.
