The latest born of this first group who attained memorable distinction in this field was Rev. Frederic Henry Hedge (1805-1890), whose earliest hymn, still in use, was written in 1829, but who is best known for his great translation of Luther’s “Ein’ feste Burg,” and for a fine Good Friday hymn. He collaborated with Rev. Frederic Dan Huntington[4] (1819-1904) then the college preacher at Harvard, in compiling _Hymns for the Church of Christ_, (1853), to which Huntington contributed five hymns, none now in use. Their book was the last and best of the various _Collections_ published up to the middle of the century by editors who belonged to what was becoming the conservative wing of the denomination, to whom Emerson’s _Divinity School Address_ of 1838 seemed dangerously radical. But meantime a new era in Unitarian hymnody was opening with the publication in 1846 of the _Book of Hymns_ edited by Samuel Longfellow (1819-1891) and Samuel Johnson (1822-1882), while they were still studying in the Harvard Divinity School. Both had come under the influence of the Transcendentalist movement which was liberalizing Unitarian thought and they eagerly sought out hymns which were fresh expressions of their youthful outlook on religion. The book was notable for the new sources of hymns which they discovered, among them the poems of John Greenleaf Whittier, which they were the first to introduce into a hymn book. Their _Book of Hymns_ was followed in 1864 by their larger and even more influential _Hymns of the Spirit_, which includes most of their own hymns and many by other Unitarian writers of the period, too numerous to name here, but whose hymns are listed in the catalogue of writers appended to this introductory sketch. Samuel Johnson wrote only half a dozen hymns, but they are among the finest in the language. Samuel Longfellow wrote many more, the best of which are quite equal to Johnson’s, and together they made a more important contribution to American Unitarian hymnody than that of any other writers in the middle of the 19^th century. This was the period of “the flowering of New England literature” and two of its poets, besides those already named, made their contribution to hymnody. The more important of the two was Dr. Oliver Wendell Holmes, (1809-1894) with half a dozen fine and widely used hymns, and Prof. James Russell Lowell (1819-1891) who, strictly speaking, was hardly a hymn writer at all, but from whose poems two or three have been quarried. Two other writers of this period were Rev. Edmund Hamilton Sears (1810-1876) and his niece, Miss Eliza Scudder (1819-1896). Sears wrote two Christmas hymns widely used throughout the English speaking world. Miss Scudder wrote half a dozen hymns in a mystical vein of the highest quality, but in temperament and outlook both writers belong more to the earlier period of Unitarian thought than to that prevalent in their later lifetime.
