Robert Louis Stevenson was born in Edinburgh in 1850, the only son of the engineer Thomas Stevenson. Despite a lifetime of poor health, Stevenson was a keen traveller, and his first book An Inland Voyage (1878) recounted a canoe tour of France and Belgium. In 1880, he married an American divorcee, Fanny Osbourne, and there followed Stevenson’s most productive period, in which he wrote, amongst other books, Treasure Island (1883), The Strange Case of Dr Jekyll and Mr Hyde and Kidnapped (both 1886). In 1888, Stevenson left Britain in search of a more salubrious climate, settling in Samoa, where he died in 1894.
