evidence: And as we remember, Nelson Mandela, we turn now to the history that shaped the former South African president. In 2004, we broadcast a series of documentaries about Mandela. We're going to hear the first installment from that series, titled "Mandela: An Audio History" by producers Joe Richman and Sue Johnson of Radio Diaries. It's told through the voices of Mandela, those who fought alongside him, and those who fought against him. Nelson Mandela was one of thousands of black South Africans who flocked to Johannesburg in the 1940s in search of work. By 1948, he was a young lawyer and activist, when a new political party came into power with a new idea: the separation of whites and blacks. It was the birth of apartheid.
