Columbia University President Lee C. Bollinger and African Studies Professor Mamadou Diouf reflect on the legacy of Nelson Mandela. "As a university long dedicated to human rights around the globe and civil rights here at home, we in the Columbia community feel acutely the loss of a true world leader like Nelson Mandela," said Bollinger. "Perhaps the greatest testament we could pay to his humility, grace and vision would be to rededicate ourselves to scholarship and action energized by his ideals of racial equality, social justice, democratic change and peaceful reconciliation."
