The nation's third president, Thomas Jefferson, founded the University of Virginia in 1819. Named Rector and Visitors of the University of Virginia, the university is known as UVa today. It is said to be Jefferson's proudest achievement and boasts an enrollment of more than 20,000 students throughout its 11 graduate and undergraduate schools. One of the most prestigious public universities in the US, the school has been noted for its law program, English department, and its more than 160-year-old, student-enforced conduct code (the Honor System). The school also includes the University of Virginia Health System, which trains future doctors and other health care workers at its Medical Center hospital.
