Ferdinand Rudolph Hassler (1770-1843) was born in Aarau, Switzerland. He was employed on the trigonometrical survey of Switzerland before he emigrated to the United States in 1805. He was acting professor of mathematics at West Point from 1807 to 1810. He was employed by the Federal Government by 1811 in an effort to begin a Coast Survey. An Act of Congress on February 10, 1807 had appropriated $50,000 to pay for the beginning of the work. Afterward, he became the first superintendent of the United States Coast Survey in 1816. Two years later, the Congress of the United States passed the control of the Coast Survey to the army, principally, where it lingered until 1832. 1805 was a common year starting on Tuesday (see link for calendar). ...

Mr. Hassler became the head of the Bureau of Weights and Measures in the Treasury Department where he carried out the early work of establishing the standards of weights and measures in the United states, with the involvement of fellow Swiss immigrant Albert Gallatin, who in 1827 brought from Europe a troy pound of brass which was made the standard of mass in 1828.

Mr. Hassler undertook a complete investigation of the national standards in 1830. Perhaps the most meaningful national standard to be adopted in 1830 was the gallon at 231 cubic inches. In the United States, however, each State retained the rights to employ its own weights and measures. Since 1830, a great deal of national legislation has been enacted, with much of it addressing the acceptance or the rejection of the metric system. The United States Bureau of Standards was created by an Act of Congress on March 3, 1901. 1830 was a common year starting on Friday (see link for calendar). ... 1830 was a common year starting on Friday (see link for calendar). ... 1830 was a common year starting on Friday (see link for calendar). ...

As mentioned above, the Coast survey languished for 14 years from 1818 to 1832. In 1823, 1824, and 1825, the Navy Department tried to establish a hydrographic office. Finally, Congress passed a law on July 10, 1832 that resulted in the removal of the Survey away from the army and the navy.
