Samuel Taylor Coleridge was born on October 21st, 1772 in Ottery St Mary, Devon, England. As a young child he was an early and devoted reader. After his father died in 1781, 8-year-old Samuel was sent to Christ's Hospital, in Greyfriars, London, where he remained throughout childhood, studying and writing poetry. From 1791 Coleridge attended Jesus College, Cambridge and in 1792, he won the Browne Gold Medal for an ode on the slave trade. In December 1793, he left the college to enlist in the Royal Dragoons using the name “Silas Tomkyn Comberbache”. His brothers arranged for his discharge a few months later and he was readmitted to Jesus College. He was introduced to political and theological ideas including those of the poet Robert Southey. In 1795, the two friends married sisters Sarah and Edith Fricker, Bristol, but Coleridge's marriage with Sarah proved unhappy. He grew to detest his wife. Coleridge made plans to establish a journal, The Watchman, to be printed every eight days in order to avoid a weekly newspaper tax. The first issue was published in March 1796; it ceased publication in May the same year.
The years 1797 and 1798, during which he lived in what is now known as Coleridge Cottage, in Nether Stowey, Somerset, were among the most fruitful of Coleridge's life. Besides the Rime of The Ancient Mariner, he composed the symbolic poem Kubla Khan, written—Coleridge himself claimed—as a result of an opium dream, in “a kind of a reverie”; and the first part of the narrative poem Christabel well as his much-praised “conversation” poems This Lime-Tree Bower My Prison, Frost at Midnight, and The Nightingale. In 1798, Coleridge and his friend William Wordsworth published a joint volume of poetry, Lyrical Ballads, which proved to be the starting point for the English romantic age. In 1800 he settled with his family and friends at Keswick in the Lake District of Cumberland to be near Grasmere, where Wordsworth had moved. Soon, however, he was beset by marital problems, illnesses, increased opium dependency, tensions with Wordsworth, and a lack of confidence in his poetic powers, all of which fuelled the composition of Dejection: An Ode and an intensification of his philosophical studies. Between 1810 and 1820, this “giant among dwarfs”, as he was often considered by his contemporaries, gave a series of lectures in London and Bristol. Much of Coleridge's reputation as a literary critic is founded on the lectures that he undertook in the winter of 1810–11 which were sponsored by the Philosophical Institution. Coleridge's ill-health, opium-addiction problems, and somewhat unstable personality meant that all his lectures were plagued with problems of delays and a general irregularity of quality from one lecture to the next. Coleridge often failed to prepare anything but the loosest set of notes for his lectures and regularly entered into extremely long digressions which his audiences found difficult to follow. In 1817, Coleridge, with his addiction worsening, his spirits depressed, and his family alienated, took residence in the Highgate home of the physician James Gillman. Gillman was partially successful in controlling the poet's addiction.
Coleridge remained there for the rest of his life. He finished the Biographia Literaria (1817), a volume composed of 23 chapters of autobiographical notes and dissertations on various subjects, including some incisive literary theory and criticism. He published other writings while he was living at the Gillman home, notably Sibylline Leaves (1817), Aids to Reflection (1825), and Church and State (1826). He died in Highgate, London on 25 July 1834 as a result of heart failure compounded by an unknown lung disorder, possibly linked to his use of opium.
