The Secretary of the Treasury is responsible for the selection of the designs, including the portraits, which appear on paper currency. The July 11, 1862 Act of Congress provided:
"That the Secretary of the Treasury be, and is hereby authorized, in case he shall think it expedient to procure said notes, or any part thereof, to be engraved, printed, and executed, in such form as he shall prescribe, at the Treasury Department in Washington, and under his direction; and he is hereby empowered to purchase and provide all machinery and materials, and to employ such persons and appoint such officers as may be necessary for this purpose."
