Robert Louis Stevenson was a Scottish novelist, essayist, poet and travel writer. 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 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.
