The Orrery Society supports the enhancement and preservation of scholarly collections at the Penn Libraries. Named for the David Rittenhouse Orrery, which maps the movements of the solar system, the Society is dedicated to the memory of Martin Meyerson, former President of Penn, President of the Friends of the Library, and a consummate library supporter.
