History
Twentieth century
During the early 1930s, the National Capital Park and Planning Commission sought to develop the section of the District of Columbia known as Foggy Bottom, located between C, E, 18th, and 23rd streets. Leading up to World War II, the expanding Department of War occupied several different buildings on the mall, making the need for a new building to consolidate operations a high priority. It was always intended to construct the building in two phases, and the Foggy Bottom site was chosen because it was large enough to accommodate both.
Gilbert Stanley Underwood and William Dewey Foster won the contract for the War Department building.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Harry S Truman Building”, the useful work is to connect “headquarters building of the United States Department of State” to the records capable of establishing context and consequence.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 13, 2026. The linked authority identifier is Q1586762. VIAF identifies the subject as 316595722. The Library of Congress control number is sh2002009507. Authority coordinates are 38.894, -77.048. 3 of 5 selected statements include explicit references; 0 carry qualifiers and 1 use preferred rank. The first chronological checks are 2000, 1941 and 2017.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
