British Nobel Prize-winning author Doris Lessing has died aged 94 at her home in London. Her best-known works include "The Golden Notebook," "Memoirs of a Survivor" and "The Summer Before the Dark." She became the oldest winner of the Nobel Prize for Literature, when in 2007, at age 88, she won the award for her life's work.

Born in what is now Iran, she moved to Southern Rhodesia, now Zimbabwe, as a child before settling in England in 1949. Her debut novel, "The Grass is Singing," was published in 1950, and she made her breakthrough with "The Golden Notebook," in 1962. The content of her other novels ranged from semi-autobiographical African experiences to social and political struggle, psychological thrillers and science fiction.
