The Hunter Thompson of the 19th Century, de Quincey is best known for his Confessions of an English Opium Eater (an activity shared with his hero, Samuel Coleridge, much to Wordsworth’s dismay). However, de Quincey’s literary genius is best captured in his essays, which, according to Wikipedia: His immediate influence extended to Edgar Allan Poe, Fitz Hugh Ludlow and Charles Baudelaire, but even major 20th century writers such as Jorge Luis Borges admired and claimed to be partly influenced by his work.
