Brown University is a private Ivy League research university in Providence, Rhode Island. Founded in 1764 as the College in the English Colony of Rhode Island and Providence Plantations, it is the seventh-oldest institution of higher education in the United States and one of the nine colonial colleges chartered before the American Revolution. At its foundation, Brown was the first college in the U.S. to accept students regardless of their religious affiliation. Its engineering program was established in 1847. It was one of the early doctoral-granting U.S. institutions in the late 19th century, adding masters and doctoral studies in 1887. In 1969, Brown adopted a New Curriculum sometimes referred to as the Brown Curriculum after a period of student lobbying. The New Curriculum eliminated mandatory "general education" distribution requirements, made students "the architects of their own syllabus" and allowed them to take any course for a grade of satisfactory or unrecorded no-credit. In 1971, Brown's coordinate women's institution, Pembroke College, was fully merged into the university; Pembroke Campus now includes dormitories and classrooms used by all of Brown. Undergraduate admissions is highly selective, with an acceptance rate of 6.6 percent for the class of 2023. The university comprises the College, the Graduate School, Alpert Medical School, the School of Engineering, the School of Public Health and the School of Professional Studies (which includes the IE Brown Executive MBA program). Brown's international programs are organized through the Watson Institute for International and Public Affairs, and the university is academically affiliated with the Marine Biological Laboratory and the Rhode Island School of Design. The Brown/RISD Dual Degree Program, offered in conjunction with the Rhode Island School of Design, is a five-year course that awards degrees from both institutions. Brown's main campus is located in the College Hill Historic District in the city of Providence, Rhode Island. The University's neighborhood is a federally listed architectural district with a dense concentration of Colonial-era buildings. Benefit Street, on the western edge of the campus, contains "one of the finest cohesive collections of restored seventeenth- and eighteenth-century architecture in the United States".
