Georgetown College, infrequently Georgetown College of Arts and Sciences, is the oldest school within Georgetown University in Washington, D.C. The College is the largest undergraduate school at Georgetown, and until the founding of the Medical School in 1850, was the only higher education division. In 1821, the school granted its first graduate degrees, though the graduate portion has since divided as the Georgetown University Graduate School of Arts and Sciences. The Georgetown Public Policy Institute, which does confer graduate degrees, is an independent Government department and Economics department initiative with its own dean. Former theology professor Chester Gillis is the Dean of the College, a position he was named to after initially serving as interim Dean while a search committee, led by University President John J. DeGioia and Provost James J. O'Donnell was underway. The previous dean, Jane Dammen McAuliffe, left to become the President of Bryn Mawr College. Alone, the college accounts for over 3,200 students, 30 academic majors with 23 departments. This forms the core of the undergraduate population.
