Lunch at the Library

Lunch at the library

Each month, the American Philosophical Society hosts a lunch presentation focused on new research and emerging topics given by APS staff or scholars from Philadelphia institutions and beyond. From the U.S. Constitution to 18th-century French mathematicians, the topics are as varied as the research interests and collections at the APS.

Lunch and the program are from 12:00 to 1:00 p.m. in Philosophical Hall (104 South Fifth Street, Philadelphia). All are welcome to attend although we ask you to RSVP to Adrianna Link at
