Dr. Martin Luther King Jr., and his wife, Coretta Scott King

Dr. Martin Luther King Jr., and his wife, Coretta Scott King, lead off the final lap to the state capitol at Montgomery, Ala., on March 25, 1965. Thousands of civil rights marchers joined in the walk, which began in Selma, Ala., on March 21, demanding voter registration rights for blacks. Rev. D.F. Reese, of Selma, is at right.
