Rittenhouse Square, one of William Penn’s original five squares, was known as the southwest square until 1825 when it was named for the astronomer-clockmaker, David Rittenhouse, a man of multiple talents and descendent of William Rittenhouse, who built the first paper mill in America in Germantown. David Rittenhouse served in the General Assembly and at the State Constitutional Convention. His survey of the Maryland-Pennsylvania boundary in 1763-64, to settle a dispute between the Penns and Lord Baltimore, was so accurate it was accepted and followed by Charles Mason and Jeremiah Dixon when they surveyed the “line” between north and south for which they are still remembered. Rittenhouse taught astronomy at the University of Pennsylvania and invented the collimating telescope; he was also president of the American Philosophical Society and the first director of the United States Mint.
