Archbishop Desmond Tutu, a legendary leader in the fight to end apartheid in South Africa, died Sunday at age 90. After Nelson Mandela was elected president in the country's first democratic election, he asked Tutu to chair South Africa's Truth and Reconciliation Commission, which examined the crimes of apartheid. Tutu preached the healing power of forgiveness. The Nobel Peace Prize-recipient spoke with Terry Gross in 1984 and 1999.
