Aaron Arrowsmith (1750–1823) was an English cartographer, engraver, publisher and founding member of the Arrowsmith family of geographers.
Life
Arrowsmith moved to Soho Square, London, from Winston, County Durham, when about twenty years of age, and was employed by John Cary, the engraver, and William Faden. He became hydrographer to the Prince of Wales and subsequently to the king in 1820. In January 1790, he made himself famous by his large chart of the world on Mercator projection. Four years later, he published another large map of the world on the globular projection, with a companion volume of explanation. Improperly attributed "Arrowsmith's projection", the globular projection used by Arrowsmith was invented by Giovan Battista Nicolosi, of Paternò, Sicily, in 1660, while Arrowsmith did not use it until 1794. The maps of North America (1796) and Scotland (1807) are the most celebrated of his many later productions.
In 1804, 63 maps drawn by Arrowsmith and Samuel Lewis of Philadelphia (publisher of William Clark's manuscript map of the Northwest) were published in the New and elegant General Atlas Comprising all Discoveries to the Present Time. Later editions of the atlas were published in 1805, 1812 and 1819. The 1804 and 1812 editions are digitised in the David Rumsey map collection.
Arrowsmith's 1808 map of the Western Hemisphere and Eastern Hemisphere was updated, corrected and enlarged by James Gardner in 1825.
