Ralph Waldo Emerson was an American essayist and poet. This is a synthetic collection covering the years 1821 to 1912 (bulk 1837-1882) with some undated material. The collection is particularly strong on poetry, including over twenty poems in manuscript, most from Emerson's earlier period. The correspondence covers a wide range of correspondents, including Amos Bronson Alcott, H.G.O. Blake, Thomas Carlyle, Horace Greeley, Nathaniel Hawthorne, Sophie Peabody Hawthorne and Henry David Thoreau. The collection also contains Whitman's notes about relations between Emerson and himself.
