Remembering Bayard Rustin: The Man Behind the March on Washington Hill, Horowitz, and Joyce Ladner, then a coordinator for the Student Nonviolent Coordinating Committee (SNCC), spoke with Throughline, to remember their days working on the march under the leadership of Bayard Rustin, the civil rights pioneer behind the March on Washington. For decades before the march, Rustin had been organizing protests, marches and sit-ins, spreading the gospel of nonviolent resistance long before Dr. King came on the national stage.
