Today on the show, a conversation with Dr. Mary Frances Berry. She is a scholar, an author and activist whose new book chronicles the history of American protest and resistance movements, from the Roosevelt administration through the Obama years. From the Vietnam War to the end of apartheid in South Africa, to her long tenure on the U.S. Civil Rights Commission that spanned several administrations, Dr. Berry brings deep experience and erudition to her fascinating book. It’s called History Teaches Us to Resist: How Progressive Movements Have Succeeded in Challenging Times.
