David Rittenhouse, born in 1732, lived here until 1770. Here he began his distinguished scientific career; and computed and observed the transit of Venus, 1769. Spent later years in Philadelphia, where he died in 1796.

Maps this old were drawn largely by eye, so places on them can sit miles from where they really are. The pin is ours and marks the marker's location today.

Example

For example, one family's tree showed the Articles of Confederation marker in Pennsylvania standing under a mile from where William Gabby lived in the 1760s.

What that marker records spans 1777 to 1789, overlapping William Gabby's years there.
