Washington, D.C., and was dedicated on May 7, 1909.After the death of Henry Wadsworth Longfellow in 1882, there were several plans to memorialize him. His bust was placed at Poets' Corner in Westminster Abbey in 1884 and a statue of the poet by Franklin Simmons was unveiled in his native town of Portland, Maine, at what became known as Longfellow Square. For the statue in Washington, an association was founded to raise money for the effort, ultimately earning $21,000 by subscribers. Additionally, Congress offered another $4,000 and the site. Members of the organization included Andrew Carnegie, Henry Cabot Lodge, Charles William Eliot, Edward Everett Hale, Julia Ward Howe, and Curtis Guild. Theodore Roosevelt served as Honorary Regent.

Doctor John Witherspoon is a bronze sculpture and granite pedestal which depicts John Witherspoon, a Presbyterian minister, member of Congress, and signer of the Declaration of Independence. Born in Scotland, Witherspoon immigrated to the U.S. in the 1760s and later became president of the College of New Jersey (now known as Princeton University). He strongly supported the Thirteen Colonies in their fight to obtain freedom from the United Kingdom of Great Britain and Ireland. Witherspoon served in the Second Continental Congress and, after the American Revolutionary War ended, in the U.S. Congress. He was the only reverend who served in Congress at that time. In 1792, Witherspoon lost his eye sight after an infection and died two years later. It wasn't until over 100 years later that plans were made to erect a statue of Witherspoon in Washington, D.C. Members of the Church of the Covenant (now known as National Presbyterian Church) and other Presbyterians formed the Witherspoon Memorial Association in 1907. After raising enough funds for the memorial, they lobbied members of Congress for permission to erect the memorial on public land. The joint resolution passed in 1908. By that time, sculptor William CouperJ had begun working on the statue. The following year the memorial was dedicated. Prominent attendees at the event included future president Woodrow Wilson, Vice President James S. Sherman, former Secretary of State John W. Foster, and British Ambassador James Bryce, 1st Viscount Bryce. The memorial is located at the intersection of 18th Street NW, Connecticut Avenue, and N Street NW, in the Dupont Circle neighborhood. The statue is bronze and depicts Witherspoon holding a Bible. On one of the memorial's pedestal is a quote from Witherspoon. When the Church of the Covenant was razed in 1966, church members wanted the statue moved to its new location, but the government denied their request. The memorial is one of 14 American Revolution Statuary collectively listed on the National Register of Historic Places and the District of Columbia Inventory of Historic Sites. The memorial is also a contributing property to the Dupont Circle Historic District and the L'Enfant Plan.

The name "M Street" refers to two major roads in the United States capital of Washington, D.C. Because of the Cartesian coordinate system used to name streets in Washington, the name "M Street" can be used to refer to any east-west street located twelve blocks north or south of the dome of the United States Capitol (not thirteen blocks, as there is no J Street). Thus, in all four quadrants of the city there are streets called "M Street", which are disambiguated by quadrant designations, namely, M Street NW, NE, SW, and SE.

The Demonet Building is composed of a historic townhouse and adjoining office building on the southeast corner of Connecticut Avenue and M Street NW in Washington, D.C. Constructed in 1880, the townhouse is the last Victorian residence on Connecticut Avenue between Dupont Circle and Farragut Square that has not been significantly altered. It features an octagonal tower topped by a dome with cartouche windows. Following a multi-year legal battle to demolish the townhouse, which had been added to the District of Columbia Inventory of Historic Sites in 1979, the Demonet Building and adjoining lot were sold for what was then a record price for downtown real estate. The adjoining office building, designed by Skidmore, Owings & Merrill, was completed in 1984. The building's namesake, John Charles Demonet, established a confectionery business on Pennsylvania Avenue in 1848. During the next several decades, he and his family grew the business into a successful company that included catering services. It was a confectionery supplier for the White House. In the early 1900s, the business was moved to Connecticut Avenue, a fashionable residential area at the time. It became a commercial pioneer of what was nicknamed the Fifth Avenue of Washington, D.C. After the business was moved a few blocks north in 1927, the Demonet family continued to own the building. It was rented to various retailers. The family sold the building in 1979. Since the modern addition was constructed, several organizations have owned the property, the most recent being an affiliate of the Qatari royal family.
