Hawthorne is a neighborhood of 308 single family homes in the Northwest quadrant of Washington, D.C. According to neighborhood lore, the subdivision was named for the hawthorn trees once abundant in the area. The neighborhood borders Montgomery County, Maryland, and is bounded by Pinehurst Tributary to the south, Western Avenue to the northwest, and Rock Creek Park to the east.This neighborhood was originally inhabited by wealthy African Americans, mostly doctors, lawyers, and professors. Most of these families were alumni and faculty of Howard University from 1969 to about 2005. Hawthorne is entirely residential, with no commercial zoning, and is occupied by 1940s-era large split-level and rambler houses on very large parcels. The neighborhood is suburban, separated from the roar of life in the nation's capital. The area is part of the Chevy Chase Citizens Association and residents consider themselves residents of Chevy Chase. The neighborhood is known for its abundance of mature trees and green space. Most of the neighborhood's housing stock was built in the 1940s. Ranch-style and split-level homes predominate, although there are some Colonial, Cape Cod, and modern-style homes.Hawthorne students are zoned to Lafayette Elementary School, Alice Deal Middle School, and Jackson-Reed High School.

Colonial Village is an area in northwest Washington, D.C., built in 1931 with 80 residences. The homes are reproductions of colonial buildings, such as the Moore House, where General Charles Cornwallis surrendered at Yorktown. The community was mostly Protestant, in contrast to the nearby 220-house North Portal Estates, which was a mostly Jewish neighborhood. When the community was first constructed in 1931, the neighborhood was exclusively populated by white Protestants as black and Jewish people were prohibited from living in Colonial Village. The land on which Colonial Village lies on, was once the 145 acre plantation of slaveowner Phillip Fenwick. After the mid-20th century, both Colonial Village and North Portal Estates became part of Shepherd Park.

The Walter Reed Army Institute of Research (WRAIR) is the largest biomedical research facility administered by the U.S. Department of Defense (DoD). The institute is centered at the Forest Glen Annex, in the Forest Glen Park part of the unincorporated Silver Spring urban area in Maryland just north of Washington, DC, but it is a subordinate unit of the U.S. Army Medical Research and Development Command (USAMRDC), headquartered at nearby Fort Detrick, Maryland. At Forest Glen, the WRAIR has shared a laboratory and administrative facility — the Sen Daniel K. Inouye Building, also known as Building 503 — with the Naval Medical Research Center since 1999. The Institute takes its name from Major Walter Reed, MD (1851–1902), the Army physician who, in 1901, led the team that confirmed the theory that yellow fever is transmitted by a particular mosquito species, rather than by direct contact. Today, the WRAIR fosters and performs biomedical research for the DoD and the US Army. It has recently developed two modern "Centers of Excellence" in the fields of military psychiatry/neuroscience and infectious disease research. The Centers focus, respectively, on soldier fitness, brain injury, and sleep management and in the development of vaccines and drugs for prevention and treatment of such diseases as malaria, HIV/AIDS, dengue fever, wound infections, leishmaniasis, enteric diseases.
