Robert Louis Stevenson (Louis like Lewis; born Robert Lewis Balfour Stevenson; 13 November 1850 – 3 December 1894) was a Scottish novelist, essayist, poet and travel writer. He is best known for the novels Treasure Island (1883), Strange Case of Dr Jekyll and Mr Hyde (1886), and Kidnapped (1893), and the poetry collection A Child's Garden of Verses (1885).
Born and educated in Edinburgh, Stevenson suffered from serious bronchial trouble for much of his life but continued to write prolifically and travel widely in defiance of his poor health. As a young man, he mixed in London literary circles, receiving encouragement from Sidney Colvin, Andrew Lang, Edmund Gosse, Leslie Stephen and W. E. Henley, the last of whom may have provided the model for Long John Silver in Treasure Island. In 1890 he settled in Samoa, where, alarmed at increasing European and American influence in the South Sea islands, his writing turned from romance and adventure fiction toward a darker realism. He died of a stroke in his island home in 1894 at age 44.
A celebrity in his lifetime, Stevenson's critical reputation has fluctuated since his death, although today his works are held in general acclaim.
