One of the Maps Consulted By Lewis & Clark
Landmark map of the United States, which includes substantial cartographic updates from the first edition.
A tremendous 4 sheet map, uncut and laid on original linen, and illustrating in great detail the extent of the United States as known immediately prior to Lewis & Clark's explorations to the west. The interior detail of the trans-Mississippi west was compiled largely from accounts supplied by Native Americans to Arrowsmith, by the Hudson's Bay Company. The course of the Missouri River delineated on the map prompted Lewis and Clark to plot their course along the Missouri River, as it appeared to be the most direct route to the Pacific.
Offered here is the edition following Arrowsmith's move to No. 10 Soho Square, in 1808. It is this edition of the map that is often referred to as the Lewis & Clark edition, as it was the edition of the map which they consulted prior to embarking on the landmark transcontinental trip.
Aaron Arrowsmith (1750-1823) was born in Durham in 1750. He came to London for work around 1770, where he found employment as a surveyor for the city’s mapmakers. By 1790, he had set up his own shop which specialized in general charts. Arrowsmith’s three shops were located on or near Soho Square, a neighborhood the led him to rub shoulders with the likes of Joseph Banks, the naturalist, and Matthew Flinders, the hydrographer. Through his business ties and employment at the HO, Arrowsmith made other important relationships with Alexander Dalrymple, the HBC, and other companies. In 1810 he became Hydrographer to the Prince of Wales and, in 1820, Hydrographer to the King. He died in 1823, whereby the business passed to his sons, Aaron and Samuel, and, later, his nephew, John.
