Benjamin Rush was a Founding Father of the United States. He lived in Pennsylvania and was a physician, writer, educator, humanitarian and devout Christian, as well as the founder of Dickinson College in Carlisle, Pennsylvania. Rush was a signatory of the Declaration of Independence and attended the Continental Congress. Later in life, he became a professor of medical theory and clinical practice at the University of Pennsylvania. Despite having a wide influence on the development of American government, he is not as widely known as many of his American contemporaries. Rush was also an early opponent of slavery and capital punishment. Despite his great contributions to early American society, Rush may be more famous today as the man who, in 1812, helped reconcile the friendship of Thomas Jefferson and John Adams by encouraging the two former Presidents to resume writing to each other. The editor of the preface of this book gives an in-depth look into Benjamin Rush’s life. The writings of Rush, which are contained in this book, show a wide range of interest and knowledge embracing agriculture and the mechanical arts, chemistry and medicine, political science, and theology. Included are letters he wrote in an effort to dispel prejudice, to fight oppression, and to elevate the lot of the lowly.
