High Quality Content by WIKIPEDIA articles! Dartmouth Medical School (DMS) is the medical school of Dartmouth College, located in Hanover, New Hampshire, in the United States. The fourth-oldest medical school in the United States, Dartmouth Medical School was founded in 1797 by New England physician Nathan Smith and grew steadily over the course of the 19th century. In the early 1900s, it was forced to cease granting the Doctor of Medicine (M.D.) degree. After further problems in the 1950s, the clinical M.D. program was reinstated and the school returned to national prominence for its academics and research. Several milestones in medical care and research have taken place at DMS, including the first clinical X-ray (1896), the first intensive care unit in the United States (1955), and the Brattleboro rat (1961).
