Columbia University in the City of New York, commonly referred to as Columbia University, is an American private Ivy League research university located in New York City, New York, United States. Columbia is the oldest institution of higher learning in the state of New York, the fifth oldest in the United States, and one of the country's nine Colonial Colleges founded before the American Revolution. Today the university operates seven Columbia Global Centers overseas in Amman, Beijing, Istanbul, Paris, Mumbai, Santiago and Nairobi.
Columbia annually administers the Pulitzer Prize and has been affiliated with more Nobel Prize laureates than any other academic institution in the world. The university is one of the fourteen founding members of the Association of American Universities, and was the first school in the United States to grant the M.D. degree. Notable alumni of the university include nine Justices of the United States Supreme Court; 20 living billionaires; 25 Academy Award winners; and 29 heads of state, including three United States Presidents.
The majority of Columbia's graduate and undergraduate studies are conducted in Morningside Heights on Seth Low's late-19th century vision of a university campus where all disciplines could be taught in one location. The campus was designed along Beaux-Arts principles by architects McKim, Mead, and White. Columbia's main campus occupies more than six city blocks, or 32 acres (13 ha), in Morningside Heights, New York City, a neighborhood that contains a number of academic institutions. The university owns over 7,800 apartments in Morningside Heights, housing faculty, graduate students, and staff.
In April 2007, the university purchased more than two-thirds of a 17 acres (6.9 ha) site for a new campus in Manhattanville, an industrial neighborhood to the north of the Morningside Heights campus. Stretching from 125th Street
to 133rd Street
, the new campus will house buildings for Columbia's schools of business and the arts and allow the construction of the Jerome L. Greene Center for Mind, Brain, and Behavior, where research will occur on neurodegenerative diseases such as Parkinson's and Alzheimer's. The $7 billion expansion plan includes demolishing all buildings, except three that are historically significant, eliminating the existing light industry and storage warehouses, and relocating tenants in 132 apartments. Replacing these buildings will be 6,800,000 square feet (630,000 m2) of space for the university.
