Robert Louis (Balfour) Stevenson (November 13, 1850- December 3, 1894), was a Scottish novelist, poet, and travel writer.

Stevenson was born Robert Lewis Balfour Stevenson in Edinburgh, Scotland. His father was Thomas Stevenson and grandfather was Robert Stevenson, both successful lighthouse engineers, and his mother was Margaret Balfour. He studied at Edinburgh Academy in his youth. His parents were both very religious. Robert gave up the religion of his parents while studying at the University of Edinburgh, but the teaching that he received as a child continued to influence him. He actually took up a branch of Christianity called Calvinism as his new religion in college.

Although ill with tuberculosis from childhood, Stevenson had a full life. He began his education as an engineer but, despite his family history, he showed little aptitude and soon switched to studying law. At the age of 18 he dropped the name Balfour and changed his middle name from Lewis to Louis (but retaining the original pronunciation); from this time on he began styling himself RLS. He turned to the law because of poor health, but he never practised. He ended his life as a tribal leader (called by his tribe Tusitala, meaning "storyteller" in Samoa) and plantation owner at his residence "Vailima" in Samoa, all this in addition to his literary career.

Stevenson's novels of adventure, romance, and horror are of considerable psychological depth and have continued in popularity long after his death, both as books and as films.

His wife Fanny Vandegrift Osbourne, whom he married in 1880, was a great support in his adventurous and arduous life.

Stevenson made several trips to the Kingdom of Hawaii and became a good friend of King David Kalakaua with whom Stevenson spent much time. Stevenson also became best friends with the king's niece Princess Victoria Kaiulani, also of Scottish heritage. Since the tragic deaths of both Stevenson and Kaiulani, historians have debated the true nature of their relationship as to whether or not they had romantic feelings for each other. Because of the age difference, such stories have often been discredited. In 1888, Stevenson travelled to the island of Molokai just weeks after the death of Father Damien. He spent twelve days at the missionary priest's residence, Bishop Home at Kalawao. Stevenson taught the local girls to play croquet. When Congregationalist and Presbyterian ministers began to defame Father Damien out of spite for his Catholicism, Stevenson wrote one of his most famous essays in defence of the life and work of the missionary priest.

Stevenson died of a cerebral hemorrhage in Vailima in Samoa, aged 44. In his will, he bequeathed his birthday to a little girl, Annie Ide, who had been born on Christmas Day.
