Dickinson College offers a four-year program of study in the liberal arts, and has about 2200 students. It was founded in 1783, the first college chartered in the newly-recognized United States of America. It was named to honorJohn Dickinson, the penman of the American Revolution and a signer of the Constitution, but the main spirit guiding the institution was Benjamin Rush. The classics department absolutely rocks.
