Lilian Passmore Sanderson

Sanderson left Sudan in 1964, after which she taught at Buckinghamshire College of Higher Education in Chalfont St Giles until 1980 and campaigned to end FGM. In 1980 she wrote a report for the University of London on "Education in the Middle East with special reference to the Sudan, Egypt and education for the eradication of female genital mutilation" and she worked with Asma El Dareer, author of a classic study on FGM in Sudan, Woman, Why Do You Weep? (1982).

In May 1960 Sanderson married George Neville Sanderson, with whom she wrote Education, Religion and Politics in Southern Sudan, 1899–1964 (1981). The couple had three children. She died of cancer in 1996.

After obtaining her diploma from Exeter, Sanderson taught at a girls' school in High Wycombe, then in 1951 accepted a post in Egypt to teach at the English Girls' College in Alexandria. From 1953 she taught at Omdurman Girls' Secondary School in Omdurman, Sudan, and from 1954 to 1958 served as headmistress of Omdurman Intermediate School. From then until 1962, she was headmistress at Khartoum Girls' Secondary School; she wrote that the school represented "the greatest single development in government secondary education for girls in the Sudan". From 1962 she taught for one year at the University of Khartoum.

Born Lilian Passmore, Sanderson attended Barnstaple Girls' Grammar School in Devon, before graduating in 1947 with a BA (as an external degree) from Exeter University College. In 1948 she obtained a Diploma of Education (DipEd), also from Exeter, and in 1962 an MA from the University of London for a thesis entitled "A history of education in the Sudan with special reference to the development of girls' schools". In 1966 she was awarded a PhD, also by the University of London; her thesis was "Education in the southern Sudan, 1898–1948".
