Sir Walter Scott, 1st Baronet, FRSE (15 August 1771 - 21 September 1832) was a Scottish historical novelist, playwright, poet and historian. Many of his works remain classics of both English-language literature and of Scottish literature. Famous titles include Ivanhoe, Rob Roy, Old Mortality, The Lady of the Lake, Waverley, The Heart of Midlothian and The Bride of Lammermoor. Although primarily remembered for his extensive literary works and his political engagement, Scott was an advocate, judge and legal administrator by profession, and throughout his career combined his writing and editing work with his daily occupation as Clerk of Session and Sheriff-Depute of Selkirkshire.

Walter Scott was born on 15 August 1771. He was the ninth child of Walter Scott, a Writer to the Signet (solicitor), and Anne Rutherford. His father was a member of a cadet branch of the Scotts Clan, and his mother descended from the Haliburton family, the descent from whom granted Walter's family the hereditary right of burial in Dryburgh Abbey. Via the Haliburton family, Walter (b.1771) was a cousin of the pre-eminent contemporaneous property developer James Burton, who was a Haliburton who had shortened his surname, and of his son, the architect Decimus Burton. Walter subsequently became a member of the Clarence Club, of which the Burtons were also members.  Five of Walter's siblings died in infancy, and a sixth died when he was five months of age. Walter was born in a third-floor flat on College Wynd in the Old Town of Edinburgh, a narrow alleyway leading from the Cowgate to the gates of the University of Edinburgh (Old College). He survived a childhood bout of polio in 1773 that left him lame, a condition that was to have a significant effect on his life and writing. To cure his lameness he was sent in 1773 to live in the rural Scottish Borders at his paternal grandparents' farm at Sandyknowe, adjacent to the ruin of Smailholm Tower, the earlier family home. Here he was taught to read by his aunt Jenny, and learned from her the speech patterns and many of the tales and legends that characterised much of his work. In January 1775 he returned to Edinburgh, and that summer went with his aunt Jenny to take spa treatment at Bath in England, where they lived at 6 South Parade. In the winter of 1776 he went back to Sandyknowe, with another attempt at a water cure at Prestonpans during the following summer.  In 1778, Scott returned to Edinburgh for private education to prepare him for school, and joined his family in their new house built as one of the first in George Square. In October 1779 he began at the Royal High School of Edinburgh (in High School Yards). He was now well able to walk and explore the city and the surrounding countryside. His reading included chivalric romances, poems, history and travel books. He was given private tuition by James Mitchell in arithmetic and writing, and learned from him the history of the Church of Scotland with emphasis on the Covenanters. After finishing school he was sent to stay for six months with his aunt Jenny in Kelso, attending the local grammar school where he met James and John Ballantyne, who later became his business partners and printed his books.
