Desmond Tutu

"Archbishop Desmond Tutu has been our moral compass and national conscience," South African President Cyril Ramaphosa said in a eulogy at Tutu's state funeral on Saturday.

South Africans from all corners of retired Archbishop Desmond Tutu's "rainbow nation" filed past his pine casket in Cape Town. The viewing line at St. George's Cathedral stretched for nearly a mile.

The archbishop is being remembered around the world for his commitment to equality and justice and his "impish" sense of humor.

Desmond Tutu will be remembered for helping end apartheid. But also for his memorable laugh, an infectious, cackling howl employed in the service of easing tensions in a very tense nation.
