1738–1807
A Scottish navigation teacher and hydrographer, he wrote one of the late 18th century’s most widely used guides for sailors. His books and charts helped shape practical seamanship at a time when long-distance sea travel was central to trade and exploration.
Born in Edinburgh in 1738 and educated in Ireland, he later joined the Royal Navy at Plymouth before building his career in London. Around 1770 he established a nautical academy at Brentford, where he taught navigation, and he also worked as a chart seller and maker of nautical instruments.
He is best known for The Practical Navigator and Seaman's New Daily Assistant, first published in 1772. The book became a popular handbook for mariners, valued for turning complicated navigation into something more usable for working sailors.
Moore also published nautical charts and served as hydrographer to the Duke of Clarence, the future William IV. He died in 1807, but his influence lasted well beyond his lifetime: his navigational work was widely used and later revised in America by Nathaniel Bowditch, linking his name to a major tradition in maritime publishing.
