Consistently ranked among the nation's top medical schools, the UCSF School of Medicine earns its greatest distinction from its outstanding faculty – among them are four Nobel laureates, 84 National Academy of Medicine members, 64 American Academy of Arts and Sciences members, 42 National Academy of Sciences members, and 18 Howard Hughes Medical Institute investigators. Founded in 1864 as Toland Medical College, the school joined the University of California in 1873, and in 1898, moved to its present Parnassus Heights campus. The first UC hospital opened here in 1907, eventually growing into Moffitt-Long Hospitals and later Benioff Children’s Hospital. These facilities, together with Mount Zion Hospital, now comprise the UCSF Medical Center.
