The LRC represented black South Africans against the apartheid state and overturned numerous discriminatory laws; Kentridge was involved in some of the Centre's landmark legal cases.
Kentridge and her husband, the prominent lawyer Sydney Kentridge, remained involved with the LRC after the end of apartheid, though they moved permanently to England in the 1980s.
In her later years, Kentridge took up painting, and her son William Kentridge became a famous artist.
