American Express was co-founded by which famous financial duo?

American Express was co-founded in 1850 by Henry Wells, William Fargo, and John Butterfield as an express mail and freight business. Wells and Fargo are especially famous because they later co-founded the banking giant Wells Fargo the following year in 1852. Although American Express eventually became best known for credit cards, travel services, and financial products, the company originally specialized in transporting valuable goods, money, and mail across the country during the expansion of the American frontier.
