Bantu Stephen Biko was born on 18 December 1946, at his grandmother's house in Tarkastad, Eastern Cape. The third child of Mzingaye Mathew Biko and Alice 'Mamcete' Biko, he had an older sister, Bukelwa, an older brother, Khaya, and a younger sister, Nobandile. His parents had married in Whittlesea, where his father worked as a police officer. Mzingaye was transferred to Queenstown, Port Elizabeth, Fort Cox, and finally King William's Town, where he and Alice settled in Ginsberg township. This was a settlement of around 800 families, with every four families sharing a water supply and toilet. Both Africans and Coloured people lived in the township, where Xhosa, Afrikaans, and English were all spoken. After resigning from the police force, Mzingaye worked as a clerk in the King William's Town Native Affairs Office, while studying for a law degree by correspondence from the University of South Africa. Alice was employed first in domestic work for local white households, then as a cook at Grey Hospital in King William's Town. According to his sister, it was this observation of his mother's difficult working conditions that resulted in Biko's earliest politicisation.
