Benjamin Rush was a signer of the United States Declaration of Independence and a civic leader in Philadelphia, where he was a physician, politician, social reformer, humanitarian, and educator and the founder of Dickinson College. Rush attended the Continental Congress. His later self-description there was: "He aimed right." He served as Surgeon General of the Continental Army and became a professor of chemistry, medical theory, and clinical practice at the University of Pennsylvania.
Rush was a leader of the American Enlightenment and an enthusiastic supporter of the American Revolution. He was a leader in Pennsylvania's ratification of the Constitution in 1788. He was prominent in many reforms, especially in the areas of medicine and education. He opposed slavery, advocated free public schools, and sought improved education for women, and a more enlightened penal system. As a leading physician, Rush had a major impact on the emerging medical profession. As an Enlightenment intellectual, he was committed to organizing all medical knowledge around explanatory theories, rather than rely on empirical methods.
