Rittenhouse Square was renamed in '''1825''' in honor of '''David Rittenhouse''' (1732-1796), one of early America's most accomplished scientists. Born in Germantown, Rittenhouse was a self-taught astronomer, mathematician, clockmaker, and instrument maker who made significant contributions to American science.

David Rittenhouse's notable achievements include:

* Observing the 1769 Transit of Venus, a critical astronomical event
* Serving as the first Director of the United States Mint (1792-1795)
* Succeeding [[Benjamin Franklin]] as president of the American Philosophical Society (1791-1796)
* Designing survey instruments used to establish state boundaries

Rittenhouse lived most of his life in Philadelphia and was buried at the Arch Street Presbyterian Church cemetery. His former observatory stood near the present-day intersection of 7th and Arch Streets.
