Elected Members

Election to the American Philosophical Society honors extraordinary accomplishments in all fields. The APS is unusual among learned societies because its Membership is comprised of top scholars from a wide variety of academic disciplines.

The APS is an elected body of scholars from all different disciplines. Today the Society has approximately 1,000 elected Members, about 850 of whom are Resident Members (are citizens of or live and work in the United States) and about 150 are International Members from more than two dozen countries. Only 5,605 Members have been elected since 1743. Since 1900, more than 240 Members have received the Nobel Prize.

Early Members included George Washington, John Adams, Thomas Jefferson, Thomas Paine, James Madison, Alexander Hamilton, and John Marshall. In the 19th century, John James Audubon, Robert Fulton, Charles Darwin, Thomas Edison, and Louis Pasteur were among those elected. Albert Einstein, Robert Frost, and George Marshall hint at the scientific, humanistic, and public accomplishments of 20th-century Members. The first woman was elected in 1789the Russian Princess Dashkova, president of the Imperial Academy of Sciences of St. Petersburg.

The photo above shows the diversity of the Society's Membership, with Michael Marletta (molecular biologist), Joyce Carol Oates (author), Stephen Lippard (chemist), Yve-Alain Bois (art historian), Martha Minow (legal scholar), and Elena Kagan (Justice of the US Supreme Court) all sitting in the front row waiting to be inducted into the Society.
