Krishnammal Jegannathan and Sankaralingam Jegannathan are two life-long activists for social justice and sustainable human development, working with those who are at the lowest rung of the social ladder. They have carried the Gandhian legacy into the 21st century, never ceasing to serve the needs of Dalits, landless and those threatened by the greed of landlords and multinational corporations. Their legacy is carried forward by their son Bhoomikumar and daughter Sathya, both doctors, serving the needy.
