Due to exhibition construction, the museum is temporarily closed.
Our First Friday event has been rescheduled to March 13.

Some of the deepest roots of scientific racism in the United States trace to the same city that birthed the nation’s independence. In this lecture, anthropologist and historian Paul Wolff Mitchell will discuss how Philadelphia became a center for the formation of racial science in the middle of the 19th century through a focus on the skull collector Samuel George Morton.

Contextualizing Morton’s cranial race science within the structures of settler-colonialism, enslavement, and medical racism across the United States, and within transatlantic discourses about race, brains, skulls, and human origins, points to the persistent legacies of scientific racism in and beyond Philadelphia today.

This Lunchtime Lecture is supported by the National Endowment for the Humanities as part of the Institute’s Innate: How Science Invented the Myth of Race project.
