Established in 1789, Georgetown is the nation’s oldest Catholic and Jesuit university. It is one of the world’s leading academic and private research institutions, offering a unique educational experience, with undergraduate degrees in forty-eight majors in the four undergraduate schools, as well as the opportunity for students to design their own individualized courses of study. The main campus is located within walking distance to Capella Washington, D.C., Georgetown, and is noted for Healy Hall, a National Historic Landmark in the Romanesque revival style. The university expanded after the American Civil War under the leadership of Patrick Francis Healy, who came to be known as Georgetown's "second founder" despite having been born a slave. The university's most notable alumni are prominent in public life in the United States and abroad. Among them are former U.S. President Bill Clinton, U.S. Supreme Court Associate Justice Antonin Scalia, numerous U.S. governors and members of Congress, heads of state or government of more than a dozen countries, royalty and diplomats.
