BUCK, Gurdon, surgeon, born in New York City, 4 May, 1807 ; died there, 6 March, 1877. He received a classical education in the schools of his native City, and engaged in business for several years; but finally, after studying medicine under Dr. Thomas Cock, he was graduated at the College of physicians and surgeons in 1830. He first served the regular term in the medical department of the New York hospital, and then went abroad to complete his professional studies, whence he returned in 1833 and began practice in New York City, where he afterward resided. During a second trip to Europe (1835-'7) he married Miss Wolff, of Geneva, Switzerland. He was successful in performing many difficult operations in surgery, and brought into general use the treatment of fractures, generally known as "Buck's extension." He was one of the oldest hospital surgeons in New York, holding the place of visiting surgeon of the New York hospital from 1837 till his death. He was also visiting surgeon of the St. Luke's and the Presbyterian hospitals, consulting surgeon of the Roosevelt hospital, and for ten years previous to 1862 visiting surgeon of the New York eye and ear infirmary. Besides being a fellow of the academy of medicine from the time it was founded, and serving one term as its vice-president, he was con-netted with the New York pathological society, the American medical association, and at different times acted as a trustee of the New York eye and ear infirmary, the College of physicians and surgeons, the New York dispensary, and the New York ophthalmic and aural institute. For thirty-five years he was a frequent contributor to medical journals. He also published an elaborate treatise entitled "Contributions to Reparative Surgery" (New York, 1876).
