Who informed American diplomats that the Louisiana Territory was for sale?
The person who informed American diplomats about the possible sale of the Louisiana Territory was Pierre Samuel du Pont de Nemours, a French economist and political figure. However, it was not until later that the negotiations for the purchase were initiated, and the deal was eventually brokered by both Robert Livingston, the American minister to France, and James Monroe, a future U.S. president.
