Stellwagen. Stellwagen was the president of the Thomas J. Fisher Companies, a real estate and mortgage brokerage closely affiliated with Senator Francis G. Newlands, and the company was in part organized to act as the fiduciary for investment by Williams Deacon's Bank to the Chevy Chase Land Company, one of the investments Newlands managed on behalf of his the descendants of his father-in-law, William Sharon. As was common at the time, the distinction between Union Trust, the Chevy Chase Land Company, and the Fisher Companies was blurred. During its early years, the Fisher Companies' brokerage office was located off a separate door at the south end of the building, and the Land Company kept offices as a tenant above.Union Trust, after several mergers, became First American Bancorp before being purchased by First Union Bank.Tenants have included the American Planning and Civic Association and Covington & Burling, which had its offices in the Old Union Trust Building in 1940, when Gerhard Gesell joined the firm (according to his 1984 unpublished memoir).

The Benjamin Ogle Tayloe House is a Federal-style house located at 21 Madison Place NW in Washington, D.C., in the United States. The house is on the northeast corner of Madison Place NW and Pennsylvania Avenue NW, directly across the street from the White House and the Treasury Building. Built in 1828 by Benjamin Ogle Tayloe, son of Colonel John Tayloe III (who built the famous Octagon House), the house became a salon for politically powerful people in the federal government. Phoebe Tayloe inherited the house upon Tayloe's death in 1868. After she died in 1881, more than 200 marble statues, bronze sculptures, fine furniture, and paintings in the house were donated to the Corcoran Gallery of Art. Phoebe Warren Tayloe's niece, Elizabeth H. Price, inherited the house in 1882 and later sold it to Senator Don Cameron of Pennsylvania for $60,000 in 1887. In around 1896, the U.S. Senate passed legislation which would have made the building the official residence of the Vice President of the United States, but the House of Representatives failed to act on the bill. Cameron leased the house to Vice President Garret Hobart from March 1897 until the fall of 1899 and the press and public nicknamed the house the "Historic Corner" and the "Cream White House" for the large number of politically important visitors and meetings held on the premises, with esteemed guests such as the International Boundary Commission and Prince Albert of Belgium. Hobart's failing health led the family to leave the Tayloe House in the fall of 1899 and Cameron then leased the home to Republican Senator Mark Hanna from January 1900 to 1902. Hanna's important political discussions of the moment with William McKinley and Theodore Roosevelt over substantial breakfasts of corned beef hash and pancakes became famous. The Congressional Union for Woman Suffrage leased the house in the fall of 1915, and made the building its headquarters for two years. The Cosmos Club had considered purchasing the house from the Tayloe family in 1885 and eventually bought it in December 1917. They vacated it in 1952 to move to their new headquarters; the building was purchased by the U.S. government and used for offices. From October 1958 until November 1961, the house was the headquarters of the National Aeronautics and Space Administration (NASA). Nearly razed to the ground in 1960 along with other buildings on Lafayette Square, successful lobbying and support from the newly elected Kennedy administration in 1961 led to the original proposals to gut the building being dropped. First Lady Jacqueline Kennedy was instrumental in persuading architect John Carl Warnecke, a friend of her husband, to create a design that would incorporate the new buildings with the old, based on the architectural theory of contextualism. The Cutts-Madison House, Cosmos Club building, and Benjamin Ogle Tayloe House were joined, and a courtyard built between them and the National Courts building. The building has remained part of the National Courts Building complex ever since, and is now listed on the National Register of Historic Places.

Wormley's Hotel was a five-story hotel at 1500 H Street, NW, Washington, D.C. It was opened in 1871. The hotel was owned by James Wormley, a free-born black man who had spent time in Europe learning fine culinary skills. The hotel became a hub for both local and foreign government officials. The hotel was the site of the Wormley Agreement, which led to the Compromise of 1877 and the election of President Rutherford B. Hayes. James Wormley died in 1884 and his son took over the business until he sold it in 1893. The hotel was later demolished and the Union Trust Company built on its site in 1906.

The Department of the Treasury (USDT) is the national treasury and finance department of the federal government of the United States where it serves as an executive department. The department oversees the Bureau of Engraving and Printing, and the U.S. Mint; these two agencies are responsible for printing all paper currency and coins, while the treasury executes its circulation in the domestic fiscal system. The USDT collects all federal taxes through the Internal Revenue Service; manages U.S. government debt instruments; licenses and supervises banks and thrift institutions; and advises the legislative and executive branches on matters of fiscal policy. The department is administered by the secretary of the treasury, who is a member of the Cabinet. The treasurer of the United States has limited statutory duties, but advises the Secretary on various matters such as coinage and currency production. Signatures of both officials appear on all Federal Reserve notes.Established by an Act of Congress in 1789 to manage government revenue, the first secretary of the treasury was Alexander Hamilton, sworn into office on September 11. Hamilton was appointed by President George Washington on the recommendation of Robert Morris, Washington's first choice for the position, who had declined the appointment. Hamilton established the nation's early financial system and for several years was a major presence in Washington's administration. The office is thus customarily referred to as "Treasury", solely, without any preceding article, as a remnant of the country's transition from British to American English during the late 18th century. Hamilton's portrait appears on the obverse of the ten-dollar bill, while the Treasury Department building is depicted on the reverse. The current secretary of the treasury is Janet Yellen, who was confirmed by the United States Senate on January 25, 2021. Jovita Carranza, appointed on April 28, 2017, was the incumbent treasurer, until January 15, 2020, when she left the office.
