Bernice Johnson Reagon was an American song leader, composer, professor of American history, curator at the Smithsonian, and social activist. In the early 1960s, she was a founding member of the Freedom Singers, organized by the Student Non-violent Coordinating Committee in the Albany Movement for civil rights in Georgia. In 1973, she founded the all-black female a cappella ensemble Sweet Honey in the Rock, based in Washington, D.C. Reagon, along with other members of the SNCC Freedom Singers, realized the power of collective singing to unify the disparate groups who began to work together in the 1964 Freedom Summer protests in the South.
