Short answers, pulled from the story.
Robert Louis Stevenson died on the 3rd of December 1894 at his home in Vailima, Samoa, at the age of 44. He collapsed while talking to his wife and died within a few hours, possibly as the result of a brain haemorrhage.
Stevenson suffered from serious bronchial trouble throughout his life, and contemporaries suspected tuberculosis. Research published in 2000 proposed that he may have suffered from hereditary haemorrhagic telangiectasia, also known as Osler-Rendu-Weber Syndrome, which could explain his chronic respiratory complaints, recurrent pulmonary haemorrhage, and early death.
Stevenson is best known for the novels Treasure Island (1883), Strange Case of Dr Jekyll and Mr Hyde (1886), and Kidnapped (1886), and for the poetry collection A Child's Garden of Verses (1885). In his later years he also wrote The Beach of Falesa and The Ebb-Tide, works that marked a turn from adventure romance toward a darker realism.
Stevenson arrived at Apia in December 1889 and settled permanently after finding the Pacific climate beneficial to his health. He and his wife Fanny purchased land at Vailima and built the islands' first two-storey house. He grew deeply involved in Samoan political life, becoming alarmed by European and American colonial encroachments, and took the Samoan name Tusitala, meaning Teller of Tales.
According to the Index Translationum, Stevenson is ranked the 26th-most-translated author in the world, a ranking recorded in 2018. This places him ahead of Oscar Wilde and Edgar Allan Poe, and just behind Charles Dickens.
For much of the 20th century Stevenson was treated as a second-class writer, relegated to children's literature and horror genres. The 1973 Oxford Anthology of English Literature omitted him entirely, and the Norton Anthology excluded him from its first through seventh editions between 1968 and 2000. A scholarly re-evaluation beginning in the late 20th century restored his standing as a literary theorist, social critic, and peer of authors such as Joseph Conrad and Henry James.
