On Sept. 15, 1963, a bomb exploded at the 16th Street Baptist Church in Birmingham, Alabama. Five girls were preparing for worship in the church basement; four were killed by the blast, but the fifth girl survived. Her name is Sarah Collins Rudolph. We talked with her about her physical and emotional scars, and about why her story is often overlooked in the larger discussions about the bombing and its role in energizing the Civil Rights Movement.
