The University of Pennsylvania (also known as Penn or UPenn) is a private Ivy League research university in Philadelphia. It identifies as the fourth-oldest institution of higher education in the United States – following the precedent of Harvard, the University of Pennsylvania dates its founding to 1740, the date of the oldest trust it administered; however, it was not established as a school until Benjamin Franklin and other Philadelphians did so in 1749, which would make it the fifth-oldest institution of higher education. The university has four undergraduate schools as well as twelve graduate and professional schools. Schools enrolling undergraduates include the College of Arts and Sciences, the School of Engineering and Applied Science, the Wharton School, and the School of Nursing. Among its highly ranked graduate schools are its law school, whose first professor James Wilson, wrote the first draft of the United States Constitution, its medical school, the first in North America, and Wharton, the first collegiate business school. Penn's endowment is US$20.7 billion, putting it amongst the wealthiest academic institutions in the world, and its 2019 research budget was $1.02 billion. Penn was one of nine colonial colleges chartered before the U.S. Declaration of Independence when Benjamin Franklin, the university's founder and first president, advocated for an educational institution that trained leaders in academia, commerce, and public service. The campus, in the University City neighborhood of Philadelphia, is centered around College Hall, and notable landmarks are Houston Hall, the first modern "student union", and Franklin Field, the first double-decker college football stadium. Penn also is the home of the Morris Arboretum, the official arboretum of the Commonwealth of Pennsylvania, which is located 15 miles northwest of the campus, in the Chestnut Hill section of Philadelphia. The university's athletics program, the Quakers, fields varsity teams in 33 sports as a member of the NCAA Division I Ivy League conference. Throughout its existence, Penn alumni, trustees, and/or faculty have included 8 signers of the Declaration of Independence, 7 signers of the U.S. Constitution, 2 Presidents of the United States, 3 U.S. Supreme Court justices, 32 U.S. senators, 163 members of the U.S. House of Representatives, 12 U.S. Cabinet Secretaries, 46 governors, 27 state Supreme Court justices, and 9 foreign heads of state.
