the Treasury to fabricate for the customhouses the standards of weights and measures established by Hassler. By reason of the joint resolution of 1836, the Office of Weights and Measures in the Coast Survey is considered formally established as of that date. He was elected a member of the American Antiquarian Society in 1838. He died on November 20, 1843, and was interred in Laurel Hill Cemetery in Philadelphia. Legacy The iron-hulled steamship Hassler, built in 1870, was named in his honor. The National Oceanic and Atmospheric Administration survey ship NOAAS Ferdinand R. Hassler (S 250) was also named for Hassler. Hassler's granddaughter, Mary Caroline Hassler Newcomb, married the noted astronomer and mathematician Simon Newcomb. Simon and Mary Caroline Hassler Newcomb were themselves the grandparents of the also much noted professor of mathematics, Hassler Whitney. Bibliography Besides several textbooks of science, Hassler produced a publication in 1828 titled A Popular Exposition of the System of the Universe. After his dismissal of the United States Survey of the Coast, Hassler proved his worth as a theorist, publishing two influential books Elements of Analytical Trigonometry and Elements of Arithmetic Theoretical and Practical. He also wrote a defense of his work on the coast survey and published it in the Transactions of the American Philosophical Society in 1825.
