Edinburgh-born Naomi Mitchison was a writer of plays, fiction, poetry and essays as well as being a passionate campaigner for a range of social and political issues. With her husband, barrister and later Labour MP, G. Richard Mitchison, she entertained a circle of intellectuals and literary friends in their house in Hammersmith and later at Carradale in Kintyre. During the 1950s and 1960s she travelled widely in India, the Middle East and Africa. Her personal involvement with the Bakgatla people of Botswana ? to which the inscription on this portrait refers ? inspired a number of writings on African issues. Mitchison was awarded a CBE in 1981. She died at Carradale in 1999, aged 101. The National Galleries of Scotland also hold a sculpture bust and an earlier portrait of Mitchison.
