DAWSON, Benjamin Franklin, physician, born in New York City, 28 June 1847. He studied at Columbia, served in the last year of the civil war as assistant surgeon in the U. S. army, and was graduated at the College of physicians and surgeons in 1866. He then established himself in New York, making a special study of obstetrics and diseases of women and children. He invented a new galvanic battery for Galvan caustic surgery in 1876, the superior qualities of which have done much to advance that branch of surgery. In 1868 he founded the "American Journal of Obstetrics and Diseases of Women and Children," which he edited until 1874. Among his publications are a translation, in conjunction with Professor Joseph Kamerer, of Klob's "Pathological Anatomy of the Female Sexual Organs" (1868)" an American edition of Barnes's " Obstetric Operations," with additions (1870)" and several monographs entitled "The Use and Comparative Merits of the Bichloride of Methyline as an Anesthetic (1874); and "Relations =between Alimentation and the Gastrointestinal Disorders of Infants and Young Children " (1875).
