Chartered by Connecticut Colony, the "Collegiate School" was established by clergy to educate Congregational ministers. It moved to New Haven in 1716 and shortly after was renamed Yale College in recognition of a gift from British East India Companygovernor Elihu Yale. Originally restricted to theology and sacred languages, the curriculum began to incorporate humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first Ph.D. in the United States in 1861 and organizing as a university in 1887.[7] Its faculty and student populations grew after 1890 with rapid expansion of the physical campus and scientific research. Yale is organized into fourteen constituent schools: the original undergraduate college, the Yale Graduate School of Arts and Sciences and twelve professional schools. While the university is governed by the Yale Corporation, each school's faculty oversees its curriculum and degree programs. In addition to a central campus in downtown New Haven, the university owns athletic facilities in western New Haven, a campus in West Haven, Connecticut and forest and nature preserves throughout New England. The university's assets include an endowment valued at $29.4 billion as of October 2018, the second largest endowment of any educational institution in the world.[2] The Yale University Library, serving all constituent schools, holds more than 15 million volumes and is the third-largest academic library in the United States.[8][9]
