" While William Penn, in the end, spent only a short period of time in Pennsylvania, in the time he was there he left an indelible mark upon the place. And when a group of men gathered together in his city of Philadelphia in 1787 to draft a constitution for the fledgling United States of America, the ideals of William Penn from nearly a hundred years before about liberty, justice, fairness, and tolerance guided much of their thinking and discussion. Indeed, Thomas Jefferson, one of the men present at that gathering, called William Penn “the greatest lawgiver the world has produced. "
