As early as 1804 Archibald McCall and E. I. du Pont were in business with each other. McCall was a prominent Philadelphia merchant involved in the East India trade, a director of the First Bank of the United States, and an agent for the sale of Du Pont powder. On April 30, 1813 the firm of Du Planty, McCall & Co. was organized with Robert McCall (a younger brother), E. I. du Pont, Victor du Pont, Raphael Du Planty as partners in a cotton spinning and weaving business. Archibald McCall and E. I. du Pont provided the capital and site for the factory. Robert McCall and Du Planty were designated as managers. The Army was the company's most important customer. However, the company was unable to compete with cheaper British textiles which flooded the U.S. after the War of 1812 and went bankrupt in the panic of 1819. It took more than 25 years for its accounts to be settled as E. I. du Pont and Raphael Du Planty could not reconcile their claims and obligations.
