ARROWSMITH, Aaron.

Aaron Arrowsmith (1750-1823) was the greatest cartographer of his day; a remarkable talent, it seems he was largely self-taught as a surveyor, before learning the publishing trade with the London maker, mapseller and publisher Andrew Dury. After working as surveyor for John Cary, he left to establish his only publishing business.

His particular specialism was wall-maps, of any and all parts of the world. He prided himself on the meticulous approach he took in preparing the maps, bringing together different sources, merging them when they overlapped, correcting them when they conflicted and rejecting details that were unreliable or unproven.

Among the many important maps that he published were two world maps, one on Mercator's Projection and one on a double-hemisphere projection, and some maps of the Americas, including this one.

Arrowsmith regularly updated this map as new information became available, incorporating the latest town names, geographical discoveries, newly-established regions, and so on, they were made available to him. In 1808, he altered his street address to 10 Soho Square, where he moved in that year. This state, the eighth recorded state, is the first to name both Michigan and Ohio.
