Jabavu, the author of seminal autobiographical, sociological and travel books, Drawn in Colour and The Ochre People, left South Africa in 1933 to further her studies in England.

In 1939 Jabavu married English film director Michael Crossfield. She became the first black female editor of The New Strand magazine in 1962. She also worked for the British Broadcasting Corporation.
