Here's a short story:

Yale University is an American private Ivy League research university in New Haven, Connecticut. Founded in 1701 in Saybrook Colony as the Collegiate School, the University is the third-oldest institution of higher education in the United States. The school was renamed Yale College in 1718 in recognition of a gift from Elihu Yale, who was governor of the British East India Company. Established to train Congregationalist ministers in theology and sacred languages, by 1777 the school's curriculum began to incorporate humanities and sciences. In the 19th century the school incorporated graduate and professional instruction, awarding the first Ph.D. in the United States in 1861 and organizing as a university in 1887. 

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, including the Yale Bowl, a campus in West Haven, Connecticut, and forest and nature preserves throughout New England. The university's assets include an endowment valued at $25.6 billion as of September 2015, the second largest of any educational institution.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.
