Doris Lessing was born in Persia (modern-day Iran) and grew up in Southern Rhodesia (modern-day Zimbabwe). Her colonial experience and her critical view of social structures profoundly shaped her writing. She moved to London in 1949 and published her first novel, 'The Grass is Singing', in 1950. Lessing wrote a vast body of work encompassing realistic fiction, science fiction (especially the 'Canopus' series), and autobiographical works. Her books frequently address themes such as colonialism, feminism, politics, psychoanalysis, and the complexities of the human condition. She was an influential literary voice and a defender of social causes, passing away in London.
