Orville Dewey was a cousin by marriage to Ralph Waldo Emerson, and was one of the few individuals privileged to call him "Waldo." He also was a friend of William Cullen Bryant and shared a pulpit with William Ellery Channing. He held one of the most influential Unitarian pulpits in the mid-19th Century. He was in favor of gradual emancipation, and incurred the wrath of Abolitionists. His correspondence with Emerson, Channing, Bryant, and others is not well known or appreciated, since his autobiography and letters are not readily available. Having his autobiography on the web is an important addition to his collected works which are already available through the "Making of America" series at the University of Michigan site.
