The bronze statue of William Penn located atop City Hall in Philadelphia.

Penn (October 14, 1644 ? July 30, 1718) was an English founder and "Absolute Proprietor" of the Province of Pennsylvania, the English North American colony and the future U.S. State of Pennsylvania. He was known as an early champion of democracy and religious freedom and famous for his good relations and his treaties with the Lenape Indians. Under his direction, Philadelphia was planned and developed.

As one of the earlier supporters of colonial unification, Penn wrote and urged for a Union of all the English colonies in what was to become the United States of America. The democratic principles that he set forth in the Pennsylvania Frame(s) of Government served as an inspiration for the United States Constitution.
