Henry Thomas, Lord Cockburn, was an Edinburgh barrister, judge and historian. A member of a distinguished legal family, he took up the post of Solicitor General for Scotland in 1830. In that role he was responsible for drafting the Scottish Reform Act of 1832, which introduced wide-ranging changes to the election laws of Scotland. He was appointed a judge in the Court of Session in 1834 and took the title Lord Cockburn. During his lifetime Cockburn published several articles on law reform, whereas his writings on Scottish social history were published posthumously. In 1830, the French silhouette artist Edouart visited Lord Cockburn at his house in Bonaly. Within four days, Edouart produced silhouettes of the entire family, including nine of the Cockburn children and the dog.
