Some of the lots during this time were developed for housing, often large homes for wealthy people, intellectuals, and high-ranking government and military officials.

The District of Columbia Organic Act of 1871 moved the city's boundary to its current size, thus Sheridan-Kalorama joined Washington, D.C. After Connecticut Avenue was extended north of Florida Avenue, streetcars lines were installed on the road, drawing more people to buy or build houses in the surrounding area.

This process has continued for decades and the neighborhood is home to dozens of embassies, ambassadorial residences, and other diplomatic buildings.

Other notable figures who have lived in the neighborhood include justices of the U.S. Supreme Court, members of Congress, presidential secretaries, and military leaders.

The surrounding neighborhoods are also historic districts, Dupont Circle to the south and east, and Kalorama Triangle to the northeast.

[2][3] Lots on the southern portion of the historic district tend to be flat, while the land gradually rises the further north one goes in the neighborhood.

One of the settlers, John Langworth, had been given a 600 acres (240 ha) tract of land in 1663 by Charles II of England.

The tract was later called Widow's Mite and owned by the Anthony Holmead family at some point in the late 18th or early 19th century.

In 1791, the City of Washington was laid out, but its furthest reach going north was Boundary Street (now Florida Avenue).

He only owned the land for a few years before selling it to poet Joel Barlow, who renamed the estate Kalorama, which means "fine view" in Greek.

Barlow had many influential people visit his estate, including President Thomas Jefferson and inventor Robert Fulton.

[2][4][5] Barlow died while on a trip to Europe, and his widow, Ruth, continued living in their house with her sister and brother-in-law Colonel George Bomford.

After Ruth's death, the property was passed on to her brother, Associate Justice of the Supreme Court Henry Baldwin.

One of the most prominent residences built during this time was an octagonal house where former Ohio Governor William Bebb lived.

Improvements were made to transportation routes and sewer lines were installed north of Boundary Street.

Massachusetts Avenue was extended past Boundary Street, before gradually making a sharp turn going northwest along modern-day Embassy Row.

Development rapidly occurred in Dupont Circle, and gradually reached farther north to Kalorama Triangle when streetcars were installed along the new portion of Columbia Road and Connecticut Avenue.

[2][4][6] Even though rowhouses were being constructed at a rapid pace in Dupont Circle, most of Sheridan-Kalorama was still rural, except for the few landowners who had not sold their properties to developers.

Examples include stand-alone houses on Wyoming Avenue, California Street, and Kalorama Road, built in 1892.

The palatial homes built along Massachusetts Avenue during the early 20th century set the tone of the neighborhood's other areas.

Ornate, larger rowhouses were built in Sheridan-Kalorama, catered to the upper class, with houses designed by local and national architects.

Amongst the people living in the neighborhood were diplomats, members of Congress, lawyers, journalists, and military officers.

Some of these buildings torn down were previously owned by noted figures, including Supreme Court Chief Justice Charles Evans Hughes and Speaker of the House of Representatives Champ Clark.

Sheridan-Kalorama had become a distinct neighborhood, with subtle differences between Dupont Circle, including house sizes, and commercial developments.

Examples include the first apartment building constructed in the neighborhood, The Highlands, in addition to The Dresden, the St Nicholas, and Windsor Lodge.

The British embassy relocated from Dupont Circle to a lot along Massachusetts Avenue, northwest of Sheridan-Kalorama.

There was minimal growth during the Great Depression, with some of the last houses along Connecticut Avenue being demolished and replaced with additional apartment buildings.

Most neighborhood citizens did not mind the presence of the embassies, but they were wary of how many other diplomatic offices and cultural centers were buying so many properties.

Due to pressure from Sheridan-Kalorama residents in the 1980s, the local government set aside 47 acres (19 ha) for embassies to be built in North Cleveland Park.

[13] Previous U.S. presidents that lived in Sheridan-Kalorama include William Howard Taft, Woodrow Wilson, Warren G. Harding, Herbert Hoover, and Franklin D.
