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''. Stevenson spent several years in search of a residence suited to his health; he travelled to various regions of the world before finally settling in Samoa, where he died.
A celebrity in his lifetime, Stevenson attracted a more negative critical response for much of the 20th century, though his reputation has been largely restored. He is currently ranked as the 26th most translated author in the world.
