THAYER, Nathaniel, clergyman, b. in Hampton, N. H., 11 July, 1769; d. in Rochester, N. Y., 23 June, 1840. His father, Rev. Ebenezer Thayer, was pastor in Hampton for many years. The son was graduated at Harvard in 1789, studied theology, and became a pastor at Wilkesbarre, Pa. In 1795 he was installed over the Unitarian society at Lancaster, Mass., where he remained for nearly fifty years. He received the degree of D. D. from Harvard in 1817. On account of Dr. Thayer's tact and sagacity he was, perhaps more than any other man of his day, selected for the settlement of ecclesiastical difficulties, and he frequently drew up the decisions of church councils. He died while on a journey for the benefit of his health. He published twenty-three occasional sermons in 1795-1831.—His son, Nathaniel, capitalist, b. in Lancaster, Mass., 11 Sept., 1808; d. in Boston, Mass., 7 March, 1883, for many years constituted, with his deceased brother, the firm of John E. Thayer and Brother, in Boston, which was active in the development of railroads in the west, of several of which he was a director. He was a fellow of Harvard in 1868-'75, and one of its largest benefactors. He contributed to a Commons hall, erected Thayer hall in 1870 as a memorial of his father and brother, bore the expenses of Prof. Louis Agassiz's expedition to South America, which was known as the Thayer expedition, built a fire-proof herbarium at the Botanic garden, and gave much in aid of poor students of the college, and was one of the most generous citizens of Boston.
THAYER, Simeon, soldier, b. in Mendon, Mass., 30 April, 1737; d. in Cumberland, R. I., 14 Oct., 1800. He removed to Rhode Island in his youth,
became an apprentice, served in the French war in 1756 with the Rhode Island troops and with Maj. Robert Rogers's rangers, and in 1757 was taken
prisoner at Fort William Henry. In May, 1775, he was appointed captain by the Rhode Island assembly, and accompanied Benedict Arnold's expedition against Quebec, where he was made prisoner. He was promoted major, 1 Jan., 1777, and served with great credit in the defence of Red Bank and at Fort Mifflin, receiving for the latter a sword from the Rhode Island assembly in July. He was wounded in the battle of Monmouth, and retired from the service, 1 Jan., 1781. His "Journal of the Invasion of Canada in 1775" has been edited
by Edwin M. Stone (Providence, 1867).

THAYER, Sylvanus, soldier, b. in Braintree, Mass., 9 June, 1785; d. in South Braintree, Mass., 7 Sept., 1872. He was graduated at Dartmouth in 1807, at the U. S. military academy in 1808, and assigned to the corps of engineers. During the next four years he was employed on engineer service on the eastern coast, and as instructor of mathematics at the academy, receiving promotion as 1st lieutenant, 1 July, 1812. Being called to the field in the latter year, he served as chief engineer under Gen. Henry Dearborn, on the Niagara frontier; in 1813 under Gen. Wade Hampton's division on Lake Champlain, receiving promotion to captain of engineers, 13 Oct., 1813, and in 1814 under Gen. Moses Porter's forces in defence of Norfolk, Va., being brevetted major, 20 Feb., 1815, for distinguished services. In 1815 he was sent to Europe to examine military works and schools, and study the operations of the allied armies before Paris, but he was recalled in 1817 to the superintendency of the academy at West Point, which he assumed on 28 July of that year, and held till his resignation, 1 July, 1833. During the sixteen years of his administration he organized the school on its present basis, and raised it from an elementary condition to the same grade with the best military schools in the world. During his term of office he was brevetted lieutenant-colonel, 3 March, 1823, made major, 24 May, 1828, and brevetted colonel, 3 March, 1833. Five years after his resignation he was again offered the charge of the academy, with almost absolute control, but he did not accept. On leaving West Point he was made a member of the board of engineers, of which he was president from 7 Dec., 1838, and for thirty years following he was engaged in the construction of defences in and about Boston harbor, which are models of his engineering skill and standards of economy and stability of construction. On 7 July, 1838, he was made lieutenant-colonel of engineers, and he became colonel, 3 March, 1863. On 1 June, 1863, he was retired from active service, after receiving the brevet of brigadier-general the day before. The degree of A. M. was conferred on him by Dartmouth in 1810, and by Harvard in 1825, and that of LL. D. by St. John's college, Md., in 1830, by Kenyon and Dartmouth in 1846, and by Harvard in 1857. He was also a member of various scientific associations. Gen. Thayer gave about $300,000 for the endowment of an academy, and $32,000 for a free library, at Braintree, and $70,000 for a school of architecture and civil engineering at Dartmouth. His body was reinterred at West Point, 8 Nov., 1877, and his statue was unveiled there, 11 June, 1883, Gen. George W. Cullum making the presentation. It bears the inscription. “Colonel Thayer, Father of the United States Military Academy,” and is represented in the accompanying illustration. A fine full-length portrait by Robert W. Weir is in the library at West Point. He was the author of “Papers on Practical Engineering” (1844). — His cousin, Martin Russell, jurist, b. in Petersburg, Va., 27 Jan., 1819, was graduated at the University of Pennsylvania in 1840, admitted to the Philadelphia bar in 1842, and began to practise in that city. In 1862-'7 he sat in congress, having been elected as a Republican, serving in the committee on the bankrupt law and as chairman of the committee on private land claims. In 1862 he was appointed a commissioner to revise the revenue laws of Pennsylvania, and in 1867, declining re-election to congress, he was appointed one of the judges of the district court of the county of Philadelphia, and he has recently been re-elected. In 1873 he was appointed on the board of visitors to West Point, and wrote the report. In the succeeding year he became president-judge of the court of common pleas of Philadelphia. He is the author of “The Duties of Citizenship” (Philadelphia, 1862); “The Great Victory: its Cost and Value” (1865); “The Law considered as a Progressive Science” (1870); “On Libraries” (1871); “The Life and Works of Francis Lieber” (1873); and “The Battle of Germantown” (1878).
