Perhaps the high point of the Civil Rights Movement was the 1963 March on Washington for Jobs and Freedom, which brought more than 250,000 marchers to the grounds of the Lincoln Memorial and the National Mall in Washington, D.C., to speak out for an end to southern racial violence and police brutality, equal opportunity in employment, equal access in education and public accommodations. The organizers of the march were called the "Big Six" of the Civil Rights Movement: Bayard Rustin the strategist who has been called the "invisible man" of the Civil Rights Movement; labor organizer and initiator of the march, A. Phillip Randolph; Roy Wilkins of the NAACP; Whitney Young, Jr., of the National Urban League; Martin Luther King Jr., of the Southern Christian Leadership Conference (SCLC); James Farmer of the Congress on Racial Equality (CORE); and John Lewis of the Student Nonviolent Coordinating Committee (SNCC). Also active behind the scenes and sharing the podium with Dr. King was Dorothy Height, head of the National Council of Negro Women.
