Nathan Trotter and Company.

Nathan Trotter and Company was a Philadelphia marketing organization which both bought and sold at wholesale. The firm succeeded William Trotter and Company, founded in 1809. The present name was first used in 1817, but the family business dates back to 1789. In the early years they dealt in a wide variety of commodities, but by the early 1830's they began to specialize in metals, primarily iron, steel, copper, brass, and tin imported from England and Wales. Later they imported from Malacca Straits, Rotterdam, and Russia, after which the domestic producers became prominent.
