William Cowper (1731-1800) was an English poet and hymnodist. One of the most popular poets of his time, Cowper changed the direction of 18th century nature poetry by writing of everyday life and scenes of the English countryside. In many ways, he was one of the forerunners of Romantic poetry. Samuel Taylor Coleridge called him "the best modern poet", whilst William Wordsworth particularly admired his poem Yardley-Oak. He was a nephew of the poet Judith Madan. Cowper suffered from severe manic depression, and although he found refuge in a fervent evangelical Christianity, the inspiration behind his much-loved hymns, he often experienced doubt and feared that he was doomed to eternal damnation. His religious sentiment and association with John Newton (who wrote the hymn Amazing Grace) led to much of the poetry for which he is best remembered.
