About APS
Today, the American Philosophical Society is a dynamic and multifaceted research institution with a mission of "promoting useful knowledge."

The Society is led by dynamic, new leadership that honors its venerable history while finding ways to increase its impact in the modern world:
  • Research: The Society plays an important role in providing independent research support to the brightest young minds -particularly important in a time when research dollars are scarcer. Its international grants and fellowship program funds over 300 scholars a year and supports research projects on all seven continents and in virtually all disciplines.
  • Unique Collections and Resources: With over 14 million pages of manuscripts, including the papers of Benjamin Franklin, the journals of Lewis and Clark, and seven Nobel Laureates, its Library is home to one of the most distinguished research collections in the United States. The Library houses four research centers and supports a museum next to Independence Hall that regularly receives 100,000 visitors from around the country.
  • The APS Press, the oldest continuously operating imprint in North America, produces a series of thought-provoking books and journals every year.
  • Convening Conversations: At the heart of the Society sits its many convenings of thought leaders who share cutting edge research in all fields of knowledge, a tradition that dates to the Society's founding.
  • A Home to Pathbreakers: As a learned society, the APS is guided and governed by its elected membership, which includes approximately 1,000 individuals who were elected because of their significant contributions to the advancement of knowledge. It is considered the most distinguished learned society in the United States. Seventeen presidents, dozens of Pulitzer Prize winners, Academy Award winners, Supreme Court justices, governors, and nearly 100 Nobel Laureates have been elected to Membership.

Collectively, the Society's work and culture embody "the life of the mind.
The Society is based on Independence National Historic Park in Philadelphia, PA. To learn more, please visit: www.amphilsoc.org
