Treasure Island was written after returning from his first trip to America where he was married. Still a relatively unknown author, inspiration came in summer of 1881 in Braemar, Scotland when bad weather kept the family inside.[3] To amuse his 12-year old stepson, Lloyd Osbourne, he used the idea of a secret map as the basis of a story about hidden treasure.
He had clearly started work by 25 August, writing to a friend, "If this don't fetch the kids, why, they have gone rotten since my day. Will you be surprised to learn that it is about Buccaneers, that it begins in the Admiral Benbow public house on the Devon coast, that it's all about a map and a treasure and a mutiny and a derelict ship... It's quite silly and horrid fun – and what I want is the best book about Buccaneers that can be had."[4]
Stevenson originally gave the book the title The Sea Cook. One month after conceiving of the book, chapters began to appear in the pages of the Young Folks magazine.[5] After completing several chapters rapidly, Stevenson was interrupted by illness.[6] He left Scotland and continued working on the first draft near London, where he and his father discussed points of the tale, and his father suggested elements that he included. The novel eventually ran in seventeen weekly installments from October 1, 1881, to January 28, 1882. The book was later republished as the novel Treasure Island and proved to be Stevenson's first financial and critical success. The Liberal politician William Ewart Gladstone, who served four terms as British Prime Minister between 1868 and 1894, was one of the book's biggest fans; it was said that he stayed up all night to read it.
The growth of the desert island genre can be traced back to 1719 when Daniel Defoe's Robinson Crusoe was published. A century later, novels such as S. H. Burney's The Shipwreck (1816), and Sir Walter Scott's The Pirate (1822) continued to expand upon Defoe's classic. Other authors in the mid-19th century continued this trend, with works including James Fenimore Cooper's The Pilot (1823). During the same period, Edgar Allan Poe wrote "MS Found in a Bottle" (1833) and "The Gold-Bug" (1843). All of these works influenced Stevenson's end product.[7]
Stevenson also consciously borrowed material from previous authors. In a July 1884 letter to Sidney Colvin, he wrote that "Treasure Island came out of Kingsley's At Last, where I got the Dead Man's Chest — and that was the seed — and out of the great Captain Johnson's History of the Notorious Pirates." Stevenson also admits that he took the idea of Captain Flint's pointing skeleton from Poe's The Gold-Bug and he constructed Billy Bones's history from the "Money-Diggers" section ("Golden Dreams" in particular[8]) of Tales of a Traveller by Washington Irving, one of his favorite writers.[9]
