English: The Colonial School for Girls, formerly known as the Schneider mansion, built in 1891 by it first occupant, noted architect Thomas Franklin Schneider. The Romanesque Revival style building was located at 1764 Q Street, N.W., on the southeast corner of 18th Street and Q Street, N.W., in the Dupont Circle neighborhood of Washington, D.C.

The Schneider family only lived in the mansion until 1894, moving to the newly constructed Cairo Apartment Building, also designed by Schneider and located two blocks east. The mansion, including much of its furnishings, was rented to the Qing legation and Envoy Wu Tingfang for a short time, followed by U.S. Senator John F. Dryden, and in 1914, the Colonial School for Girls. The finishing school continued renting the facility until 1930, when the mansion was converted into a boarding house. In 1958, the 67-year-old mansion was demolished to provide parking spaces. The site is now occupied by a nine-story apartment building, the Dupont East, constructed in 1961.
