James Boswell (1740-1795) was a lawyer, diarist, and author born in Edinburgh, Scotland. He was the eldest son of a judge, Alexander Boswell of Auchinleck, Lord Auchinleck. He is best known as the biographer of Samuel Johnson. His name has passed into the English language as a term (Boswell, Boswellian, Boswellism) for a constant companion and observer.
Boswell is known for taking voracious notes on the grand tour of Europe that he took as a young nobleman.
His manuscripts have been collected by Yale University.
