Bernice Johnson Reagon, a civil rights activist who co-founded The Freedom Singers and later started the African American vocal ensemble Sweet Honey in the Rock, died Tuesday at the age of 81. Her daughter, the acclaimed musician Toshi Reagon, shared the news of her mother's passing Wednesday night in a public Facebook post. It is impossible to separate liberation struggles from song. And in the 1960s — at marches, and in jailhouses — the voice leading those songs was often Bernice Johnson Reagon. Her work as a scholar and activist continued throughout her life, in universities and concert halls, at protests and in houses of worship. The future songleader was born in southwest Georgia, the daughter of a Baptist minister. She was admitted to a historically Black public college, Albany State, at the age of 16 and studied music. Albany, Ga., would become an important center of the civil rights movement when the Rev. Martin Luther King Jr. was arrested there in 1962, causing the media to descend on the town.
