BIOGRAPHY
Percy Bysshe Shelley (1792-1822). Born near Horsham, England, Shelley was the son of a wealthy landowner who sat in Parliament. At University College, Oxford, he befriended Thomas Jefferson Hogg. Both became interested in radical philosophy and quickly became inseparable. After one year at Oxford they were expelled together for writing and circulating a pamphlet entitled "The Necessity of Atheism." Shelley married Harriet Westbrook soon after leaving Oxford. Though they had two children, the marriage was unsuccessful, and in 1814, Shelley left Harriet for Mary Wollstonecraft Godwin (author of Frankenstein [1818]). After Harriet's death (an apparent suicide), Shelley and Godwin were married.

Escaping legal problems in England, he settled in Pisa, Italy, in 1820, and died in a sailing accident before his thirtieth birthday. A playwright and essayist as well as a romantic poet, Shelley is admired for his dramatic poem "Prometheus Unbound" (1820).
