Percy Bysshe Shelley was a British writer who is considered as one of the major English Romantic poets. A radical in his poetry as well as in his political and social views, Shelley did not achieve fame during his lifetime, but recognition of his achievements in poetry grew steadily following his death, and he became an important influence on subsequent generations of poets, including Robert Browning, Algernon Charles Swinburne, Thomas Hardy, and W. B. Yeats. American literary critic Harold Bloom describes him as "a superb craftsman, a lyric poet without rival, and surely one of the most advanced sceptical intellects ever to write a poem."

Harold Bloom was an American literary critic and the Sterling Professor of humanities at Yale University. In 2017, Bloom was called "probably the most famous literary critic in the English-speaking world". After publishing his first book in 1959, Bloom wrote more than 50 books, including over 40 books of literary criticism, several books discussing religion, and one novel. He edited hundreds of anthologies concerning numerous literary and philosophical figures for the Chelsea House publishing firm. Bloom's books have been translated into more than 40 languages. He was elected to the American Philosophical Society in 1995.
