Streets of Washington, written by John DeFerrari, covers some of DC’s most interesting buildings and history. John is the author of Historic Restaurants of Washington, D.C.: Capital Eats, to be published this September by the History Press, Inc. John is also the author of Lost Washington DC.
One of the country’s most sophisticated scientific laboratory complexes, the National Bureau of Standards, once stood on a hill off of Connecticut Avenue at Upton Street, in the serene, semi-rural upper Northwest section of the city. Through much of the 20th century, this secluded and unassuming enclave quietly made countless important contributions to the safety and quality of the manufactured goods we take for granted today, including everything from airplane engines to kitchen crockery.

Connecticut Avenue runs along the top of this circa 1930 view of the Bureau’s campus (Author’s collection).
The Bureau was founded in 1901, during a period of burgeoning industrial production and dramatic technological change. Telephones, automobiles, light bulbs, electrical machinery—it all needed practical, reliable standards based on methodical scientific testing. The new Bureau filled this need, greatly expanding on the mission of its predecessor, the Office of Weights and Measures, which had been set up in the Treasury Department in the early 19th century to ensure that standard measures were used when calculating customs duties on imported goods.
First housed temporarily in the old Office of Weights and Measures building on Capitol Hill, the fledgling Bureau in 1901 urgently needed space to build its own laboratory. The requirements were exacting. The laboratory had to be well outside the city proper, somewhere completely free from vibration, traffic disturbances, and the electrical interference caused by streetcar lines. It had to be solidly built, using twice the construction materials of an ordinary office building, heating and plumbing lines that were twice as complicated as an average building’s, and four or five times the usual amount of wiring. Some labs were to be fitted out with both running salt water and fresh water as well as dispensed crushed ice. Ancillary buildings would also be needed for engines, pumps, heavy machinery, and the fabrication of sensitive scientific instruments. (more…)
