James Tytler (born December 17, 1745, Fearn, Forfarshire [now Angus], Scotland—died January 11, 1804, Salem, Massachusetts, U.S.) was a Scottish editor of the Encyclopædia Britannica’s second edition, who was sometimes called “Balloon Tytler” because of his experiments in aeronautics.
Known in Edinburgh as a debt-ridden eccentric, between 1776 and 1784 Tytler almost single-handedly revised the original edition of the Encyclopædia Britannica, enlarging it from 3 to 10 volumes, including historical and biographical material for the first time. He was one of the first men in Britain to attempt a balloon ascension (August 1784). A political radical, he was forced to emigrate in 1792 because a handbill he had printed was deemed seditious. Tytler ended his days as a newspaper publisher in the United States.
