Public higher education is provided by the many campuses of the City University of New York (CUNY) and the State University of New York (SUNY). CUNY is built around the City College of New York, whose own history dates back to the formation of the Free Academy in 1847. Much of CUNY's student body, which represent 197 countries, consists of new immigrants to New York City. CUNY has campuses in all of the five boroughs, with 11 four-year colleges, 7 two-year colleges, a law school, a graduate school, a medical school, an honors college, a public health school, professional studies school, and a journalism school. A third of college graduates in New York City are CUNY graduates, with the institution enrolling about half of all college students in New York City. The City University's alumni include Jonas Salk, Colin Powell, Paul Simon and Art Garfunkel.
