From the New York Times:
Albertina Sisulu, considered by many to be the mother of South Africa's liberation struggle, a woman who was hounded and jailed by the apartheid government but who lived to see her children assume leadership roles in a democratic nation, died here on Thursday. She was 92.
The African National Congress confirmed her death.
Mrs. Sisulu's passing extinguishes another light of a generation that fought one of the great moral battles of the 20th century. Since her death, virtually every one of this nation's leaders have come to her home to offer condolences. Only Nelson Mandela has been conspicuously absent. He is increasingly frail, and members of the Sisulu family visited him instead.
A humble but forceful woman, Mrs. Sisulu was the widow of Walter Sisulu, one of Mr. Mandela's earliest political mentors, who died in 2003. She kept her dignity through decades of government harassment. Mr. Sisulu was imprisoned for 26 years, and she herself was repeatedly jailed, held incommunicado and "banned," a restriction limiting where she could go and how many people she could see.
"But try as they might, they could not break her spirit, they could not make her bitter, they could not defeat her love," Archbishop Emeritus Desmond Tutu said in one of the many tributes offered after her death.Read more here.
