Kings College was founded in 1754 by royal charter from King George II, one of six colleges in the American colonies at the time. The others were Harvard, William and Mary, Yale, University of Pennsylvania, and Princeton. As a result of nationalistic sentiments which culminated in the American Revolutionary War, the college was renamed Columbia College, after Christopher Columbus. The Medical Department of King's College was founded in 1767. This was the second medical school in the American colonies and the first to grant a medical degree. In 1807, the College of Physicians and Surgeons (P&S) was founded as a rival institution in the City of New York, but in 1813 it merged with Columbia College's Medical Department. The new entity became known as P&S. The Presbyterian Hospital (PH) was founded in 1868. In 1928, the Hospital moved from its first location at 70th Street and Park Avenue to its present site in Washington Heights on the banks of the Hudson River. In moving, the PH joined with P&S at a time when the academic medical center was a new concept. The resulting Columbia-Presbyterian Medical Center was the first such academic medical center in the United States.
