Ichabod Nichols, an American clergyman, born in Portsmouth, N. H., July 5, 1784, died in Cambridge, Mass., Jan. 2, 1859. He graduated at Harvard college in 1802, and from 1805 to 1809 was tutor there in mathematics. On Jan. 7, 1809, he was ordained as associate pastor of the first Congregational church in Portland, Me., and was sole pastor from 1814 to 1855, when he received a colleague, and afterward, though retaining his pastorate, resided in Cambridge. He received the degree of D. D. from Bowdoin college in 1821, and from Harvard college in 1831; and he was for many years one of the trustees of Bowdoin college. He was also for several years vice president of the American academy of arts and sciences. In 1830 he published a work on natural theology, and he left a work nearly ready for the press, entitled "Hours with the Evangelists" (2 vols. 8vo, Boston, 1859-'64), which embraces an argument for the Christian revelation and miracles, directed mainly against the Straussian theory, and a series of critical and philosophical comments on the principal epochs in the life of Jesus. A volume entitled "Remembered Words from the Sermons of the Rev. I. Nichols" appeared in Boston in 18G0.
