First Lady Rosalynn Carter, though a constant presence at her husband side, has blazed her own trail through her advocacy for causes such as mental health, refugee welfare, immunizations, voting rights, caregivers and housing, to name just a few. Here are photos from an amazing life that has taken her from Plains, Ga., through the governor's mansion and White House, and around the world. This portrait was taken in the White House in 1979.
