This position in the Federal Government of the United States is analogous to the Minister of Finance in many other countries.  The Secretary of the Treasury is a member of the President's Cabinet, and is nominated by the President of the United States.  Nominees for The Secretary of the Treasury undergo a confirmation hearing before the United States Senate Committee on Finance before being confirmed by the United States Senate.

T. A. D. Fessenden: Thomas Amory Deblois Fessenden (January 23, 1826 – September 28, 1868) was a U.S. Representative from Maine, the son of abolitionist legislator Samuel Fessenden, and brother of Treasury Secretary William P. Fessenden and congressman Samuel C. Fessenden.  He was an uncle of Union Army generals Francis Fessenden and James D. Fessenden.

Samuel C. Fessenden: Samuel Clement Fessenden (March 7, 1815 – April 18, 1882) was a United States Congressman from Maine, son of abolitionist Samuel Fessenden, and brother of Treasury Secretary William Pitt Fessenden and Congressman T. A. D. Fessenden.  He was an uncle of Union Army generals, Francis Fessenden and James D. Fessenden.

William P. Fessenden: William Pitt Fessenden (October 16, 1806September 8, 1869) was an American politician from the U.S. state of Maine.  Fessenden was a Whig (later a Republican) and member of the Fessenden political family.

Randal Quarles: Randal Keith Quarles (born September 5, 1957 in San Francisco) is founder and head of The Cynosure Group, a private investment firm backed by a network of large family offices in the United States.  Before founding Cynosure, he was a partner of The Carlyle Group, one of the world's largest private equity firms.  From August 2001 until October 2006, he held several important financial policy posts in the George W. Bush administration, ultimately serving as Under Secretary of the Treasury for Domestic Finance.  As Under Secretary, he was the lead advocate for imposing greater regulation on Fannie Mae and Freddie Mac, arguing that they posed significant risk to the financial sector, and argued for fundamental reform of the entire financial regulatory system—extending broader and more uniform federal regulation to investment banks and insurance companies—because the current system restricted regulators' ability to observe and limit risk in the system.  In his earlier positions in the administration he had a key role in response to several international crises—the Argentine debt default, as well as near defaults in Brazil, Turkey and Uruguay—and chaired the international working group that led to changes in the terms of sovereign debt finance that now permit collective action by creditors in such crises.  He also argued strongly for improving international coordination of financial regulation, initiating a regular dialogue with the European Union on financial regulatory matters and representing the United States at the Financial Stability Forum.  He negotiated the historic debt relief agreement for the world's poorest countries reached at the G7 Meetings in London during 2005.  In prior government service, he was an important member of the team developing the government's response to the savings and loan crisis of the late 1980s and early 1990s.  At the time of his departure from government, Hank Paulson, the Treasury Secretary, noted that he had played a role in an unusually large range of matters in the history of the Treasury – "from the Argentine debt default to terrorism risk insurance, and from Chinese currency flexibility to GSE reform", and awarded him the Alexander Hamilton Medal, the Treasury Department's highest honor.  He is widely mentioned as a possible Treasury Secretary or senior White House adviser in any future Republican administration.

Lot M. Morrill: Lot Myrick Morrill (May 3, 1813January 10, 1883) was an American statesman who served as the 28th Governor of Maine, in the United States Senate and as Secretary of the Treasury appointed by President Ulysses S. Grant.  Morrill was an accomplished politician serving several elected and appointed offices throughout his lifetime.  Morrill, as Secretary of Treasury, was devoted to hard currency rather than paper money and dedicated himself to serve the public good rather than party interests.  Morrill was popularly received as Treasury Secretary in the American press and Wall Street, known for his financial and political integrity.  Morrill was President Grant's fourth and last U.S. Secretary of the Treasury.

Secretary to the Treasury: In the United Kingdom, there are several Secretaries to the Treasury, who are Treasury ministers nominally acting as secretaries to HM Treasury.  The origins of the office are unclear, although it probably originated during Lord Burghley's tenure as Lord Treasurer in the 16th century.  The number of secretaries was expanded to two by 1714 at the latest.  The Treasury ministers together discharge all the former functions of the Lord Treasurer, which are nowadays nominally vested in the Lords Commissioners of the Treasury.  Of the Commissioners, only the Second Lord of the Treasury, who is also the Chancellor of the Exchequer, is a Treasury minister (the others are the Prime Minister and the Government Whips).  The Chancellor is the senior Treasury minister, followed by the Chief Secretary to the Treasury, who also attends Cabinet and has particular responsibilities for public expenditure.  In order of seniority, the junior Treasury ministers are: the Financial Secretary to the Treasury; the Economic Secretary to the Treasury; the Exchequer Secretary to the Treasury; and the Commercial Secretary to the Treasury (Office currently not in use).  One of the present-day secretaries, the Parliamentary Secretary to the Treasury, formerly known as the 'Patronage Secretary', is not a Treasury minister but the Government Chief Whip in the House of Commons.  The office can be seen as a sinecure, allowing the Chief Whip to draw a government salary, attend Cabinet, and use a Downing Street residence.
