BRUNSWICK — Educator and activist Angela Davis is scheduled to speak today at Bowdoin College.

The 1960s radical will appear in the Brunswick school’s Pickard Theater for a presentation called “A Conversation with Angela Davis.” Admission is free but tickets are required.

In January, Davis told students at the University of New Hampshire at a Martin Luther King Jr. event that the racial imbalance in American prisons is oppressive to minorities.

Davis was once a member of the Black Panthers, the Student Nonviolent Coordinating Committee and the Communist Party. She was acquitted of murder and kidnapping charges in California in 1972. Since then, Davis has become a university professor and does extensive research on prisons and minorities.
