Graça Machel, DBE (born Graça Simbine; 17 October 1945) is a Mozambican politician, humanitarian and international advocate for women’s and children’s rights.

She was the third wife and now the widow of former South African president Nelson Mandela, as well as the widow of the late Mozambican president Samora Machel.

She is the only woman in the world to have served as the First Lady of two different nations.

It is 2004.  You’ll find me sitting in a one room metal shack owned by a woman named Zolecka Ntuli in a township outside of Cape Town.

I’d gone to South Africa on a personal journey to learn more about HIV/AIDS.

I spent a month crisscrossing the country, interviewing social workers, health care workers, NGOs, social entrepreneurs, academics, business leaders and individuals.
