Walter Channing, an American physician, brother of the preceding, born at Newport, R. I., April 15, 1786. He entered Harvard college in 1804, but left in his junior year on account of the college dispute of 1807. He studied medicine in Boston and Philadelphia, received the degree of M. D. from the university of Pennsylvania, afterward studied at the university of Edinburgh, and at Guy's and St. Thomas's hospitals in London, and began practice in Boston in 1812. The same year he was appointed lecturer, and in 1815 professor, of obstetrics and medical jurisprudence in Harvard university, which office he filled until his resignation in 1854. In 1821 he became assistant of Dr. James Jackson as physician of the newly established Massachusetts general hospital, and labored there for nearly 20 years. He has been a frequent contributor to medical and literary periodicals, besides publishing "Etherization in Childbirth," illustrated by 581 cases (Boston, 1848); a volume of "Miscellaneous Poems" (1851); and "A Physician's Vacation, or a Summer in Europe" (1856). The treatise on "Etherization in Childbirth" attracted great attention both in Europe and America, and had a marked effect on the state of that branch of science.
Subsequently he published "Professional Reminiscences of Foreign Travel," "New and Old," and "Reformation of Medical Science" (1857).
