Aaron Arrowsmith (1750-1823)
Initially a land surveyor and worked for other map publishers. In 1790 he set up on his own as a publisher and engraver. His first map was a world map showing all the recent discoveries and foreshadowed his future direction. All his working life he produced maps with the most recent discoveries and information. These were supplied from information given by explorers and travellers who often gave him their manuscripts to include in his maps.
