It says a lot that the University of Virginia (UVa) is Thomas Jefferson's proudest achievement. The nation's third president (as well as inventor, philosopher, and author, among other titles) founded the school in 1819. With just over 20,000 students enrolled in its 11 graduate and undergraduate schools, UVa is 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.
