History & History Related Items

Founded: 1790

Washington, D.C. was designed by Major Pierre Charles L'Enfant around 1791. It was the first American city planned for a specific purpose. It was designed to be a beautiful city with wide streets and many trees. The city's business is centered around the government. Another name for Washington, D.C. is the District of Columbia. The district was originally a 10 miles square crossing the Potomac River into Virginia. Both Virginia and Maryland donated part of their land for the capital district. The Virginia portion of D.C. was later ceded back to Virginia.

Washington as it Was!
Photographs by Theodor Horydczak (1923-1959)
Spanning from the mid 1920s through the 1950s, the Theodor Horydczak collection (about 14,350 photographs online) documents the architecture and social life of the Washington metropolitan area in the 1920s, 1930s, and 1940s, including exteriors and interiors of commercial, residential, and government buildings, as well as street scenes and views of neighborhoods. A number of Washington events and activities, such as the 1932 Bonus Army encampment, the 1933 World Series, and World War II preparedness campaigns, are also depicted.
