Robert Louis Stevenson was born to Thomas and Margaret Isabella Balfour Stevenson in Edinburgh on 13 November 1850. From the beginning he was sickly. Through much of his childhood he was attended by his faithful nurse, Alison Cunningham, known as Cummy in the family circle. She told him morbid stories about the Covenanters (the Scots Presbyterian martyrs), read aloud to him Victorian penny-serial novels, Bible stories, and the Psalms, and drilled the catechism into him, all with his parents' approval. Thomas Stevenson was quite a storyteller himself, and his wife doted on their only child, sitting in admiration while her precocious son expounded on religious dogma. Stevenson inevitably reacted to the morbidity of his religious education and to the stiffness of his family's middle-class values, but that rebellion would come only after he entered Edinburgh University.
