Horatio Walpole, 4th Earl of Orford — also known as Horace Walpole — was an English art historian, man of letters, antiquarian and Whig politician. He is now largely remembered for Strawberry Hill, the home he built in Twickenham, south-west London where he revived the Gothic style some decades before his Victorian successors, and for his Gothic novel, The Castle of Otranto. Along with the book, his literary reputation rests on his Letters, which are of significant social and political interest. He was the son of Sir Robert Walpole, and cousin of Lord Nelson.
