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.
