Ad′amites, a religious sect dating from the second century, probably of Gnostic origin. It was so called because both men and women were said to appear naked in their assemblies, either to imitate Adam in the state of innocence or to prove the control which they possessed over their passions. Practices similar to those of the Adamites arose several times in later ages. See Beghards.
Adam′nan, St., born in Ireland about 624, was elected abbot of Iona in 679, and died there about 703 or 704. He is best known from his Life of St. Columba, valuable as throwing light on the early ecclesiastical history of Scotland. (There are editions by Reeves, 1857; reissued with English translation 1874; and by Fowler, 1895.) His feast is celebrated on 23rd Sept.
Adams, Charles Francis, American litterateur and statesman, was a son of John Quincy Adams, and was born in 1807. His boyhood was spent in Europe, partly in England; but he finished his education at Harvard, and afterwards studied law. After serving some years in the Massachusetts legislature he was sent to Congress in 1859. In 1861 Lincoln sent him to England as American minister, and here he remained for seven years, performing the arduous duties of his office with the utmost tact and ability. Between 1874 and 1877 he edited a complete edition of his grandfather's works in 12 vols. He was one of the arbitrators on the Alabama claims. Died in 1886.
Adams, John, second president of the United States, was born at Braintree (now Quincy), Massachusetts, 19th Oct., 1735. He was educated at Harvard University, and adopted the law as a profession. His attention was directed to politics by the question as to the right of the English Parliament to tax the colonies, and in 1765 he published some essays strongly opposed to the claims of the mother country. As a member of the new American congress in 1774, 1775, and 1776 he was strenuous in his opposition to the home Government, and in organizing the various departments of the colonial Government. On 13th May, 1776, he seconded the motion for a declaration of independence proposed by Lee of Virginia, and was appointed a member of committee to draw it up. The declaration was actually drawn up by Jefferson, but it was Adams who fought it through Congress. In 1778 he went to France on a special mission, but soon came back and again returned, and for nine years resided abroad as representative of his country in France, Holland, and England. After taking part in the peace negotiations he was appointed, in 1785, the first ambassador of the United States to the Court of St. James. He was recalled in 1788, and the following year elected vice-president of the republic under Washington. In 1792 he was re-elected vice-president, and at the following election in 1797 he became president in succession to Washington. The commonwealth was then divided into two parties, the Federalists, who favoured aristocratic and were suspected of monarchic views, and the Republicans. Adams adhered to the former party, with which his views of government had always been in accordance, but the real leader of the party was Hamilton, with whom Adams did not agree, and who tried to prevent his election. His term of office proved a stormy one, which broke up and dissolved the Federalist party. His re-election in 1801 was again opposed by the efforts of Hamilton, which ended in effecting the return of the Republican candidate Jefferson. Thus it happened that when Adams retired from office his influence and popularity with both parties were at an end, and he sunk at once into the obscurity of private life. He had the consolation, however, of living to see his son president. He died 4th July, 1826, the fiftieth anniversary of the declaration of independence, and on the same day as Jefferson. His works have been ably edited by his grandson Charles Francis Adams.
Adams, John Couch, English astronomer, born 1819, died 1892, studied at Cambridge, and was senior wrangler in 1843. His investigations into the irregularities in the motion of the planet Uranus led him to the conclusion that they must be caused by another more distant planet, and the results of his labours were communicated in September and October, 1845, to Professor Challis and Airy the Astronomer Royal. The French astronomer Leverrier had by this time been engaged in the same line of research, and had come to substantially the same results,
which, being published in 1846, led to the actual discovery of the planet Neptune by Galle of Berlin. In 1858 Adams was professor of mathematics at Aberdeen University, and in 1859 was appointed Lowndean professor of astronomy and geometry at Cambridge.
Adams, John Quincy, sixth president of the United States, son of John Adams, second president, was born 11th July, 1767. Accompanying his father to Europe he received part of his education there, but graduated at Harvard in 1788. Having adopted the legal profession, in 1791 he was admitted to the bar. He now began to take an active interest in politics, and some letters that he wrote having attracted general attention, in 1794 Washington appointed him minister to the Hague. He afterwards was sent to Berlin, and also on a mission to Sweden. In 1798 he received a commission to negotiate a treaty of commerce with Sweden. On the accession of Jefferson to the presidency in 1801 he was recalled. The Federalist party (that of his father), which was now declining, had sufficient influence in Massachusetts to elect him to the senate in 1803. On an important question of foreign policy, that of embargo, he abandoned his party, and having lost his re-election on this account, he retired to the professorship of rhetoric at Cambridge, which he held from 1806 to 1809. In 1809 he went as ambassador to Russia. He assisted in negotiating the peace of 1814 with England, and was afterwards appointed resident minister at London. Under Monroe as president he was secretary of state, and at the expiration of Monroe's double term of office he succeeded him in the presidency (1825). He was not very successful as president, and at the end of his term (1829) he was not re-elected. In 1831 he was returned to Congress by Massachusetts, and continued to represent this State till his death, his efforts being now chiefly on behalf of the Abolitionist party. He died 21st Feb., 1848.
