History NewYork-Presbyterian Hospital was founded in 1771 as New York Hospital by Edinburgh Medical School graduate Samuel Bard. It received a Royal Charter granted by King George III of Great Britain and became associated with Weill Cornell Medical College upon Weill Cornell's founding in 1898. It is the third oldest hospital in the United States, after NYC Health + Hospitals/Bellevue in New York City (1736) and Pennsylvania Hospital (1751). A 1927 endowment of more than $20 million by Payne Whitney expanded the hospital significantly and the Payne Whitney Psychiatric Clinic is named in his honor. Other prominent donors have included Howard Hughes, William Randolph Hearst, Harry and Leona Helmsley, Maurice R. Greenberg, and the Baker, Whitney, Lasdon, and Payson families. The Presbyterian Hospital was founded in 1868 by James Lenox, a New York philanthropist and Columbia University College of Physicians and Surgeons, also founded by Samuel Bard in 1767. In 1910, Columbia University and Presbyterian Hospital reached an agreement to affiliate, forming the world's first academic health center through the merger of existing institutions. During the 1920s, Edward S. Harkness and Anna Harkness purchased land and funded the construction of Columbia-Presbyterian Medical Center. In 1928, the two institutions fully moved to the new medical center. In 1925, the Sloane Hospital for Women, a leader in obstetrics and gynecology that had been founded in 1886, was incorporated. In 1928, Sloan, along with The Squier Urological Clinic and the Vanderbilt Clinic, moved to Columbia Presbyterian Medical Center.
