In 1789, the United States Constitution granted Congress the power to fix standards of weights and measures. President George Washington spoke on this issue in his first annual message to Congress in January 1790. He stated that uniformity in currency and measurements was an object of great importance. The Articles of Confederation had previously given colonies the right to regulate coinage and set weight standards. By 1838, the federal government finally adopted a uniform set of standards after decades of debate. An Office of Standard Weights and Measures operated within the Treasury Department from 1830 until 1901. This office was part of the Survey of the Coast which later became the United States Coast and Geodetic Survey.
Evolution Of The Bureau
Congress passed a bill proposed by Congressman James H. Southard in 1901 to establish the Bureau of Standards. Theodore Roosevelt appointed Samuel W. Stratton as the first director with an initial budget of $40,000. The new agency took custody of kilogram and meter bars used as US measurement standards. A laboratory site was constructed in Washington DC using instruments acquired from European national physical laboratories. Herbert Hoover directed the bureau during World War I to develop commercial standards for materials and products. The bureau produced optical glass when European supplies were cut off during the war. Harry Diamond developed a blind approach radio aircraft landing system between the world wars. Military research included proximity fuzes and radar-guided anti-ship bombs during World War II.
