United States Department of the Treasury

The Department of the Treasury (DoT) is an executive department and the treasury of the United States federal government. It was established by an Act of Congress in 1789 to manage government revenue. The Department is administered by the Secretary of the Treasury, who is a member of the Cabinet. Jacob J. Lew is the current Secretary of the Treasury; he was sworn in on February 28, 2013.

The first Secretary of the Treasury was Alexander Hamilton, who was sworn into office on September 11, 1789. Hamilton was asked by President George Washington to serve after first having asked Robert Morris (who declined, recommending Hamilton instead). Hamilton almost single-handedly worked out the nation's early financial system, and for several years was a major presence in Washington's administration as well. His portrait is on the obverse of the U.S. ten-dollar bill while the Treasury Department building is shown on the reverse.

Besides the Secretary, one of the best-known Treasury officials is the Treasurer of the United States whose signature, along with the Treasury Secretary's, appears on all Federal Reserve notes.
