At an age when most people would think about retirement, Cicely Williams continued with boundless energy in a career of research and teaching, in London, at the American University of Beirut, with the Family Planning Association, and Tulane University. She conducted surveys on child health in Borneo, Italy, Yugoslavia, Tanzania, Cyprus and Uganda. She worked with Palestinian mothers and children in the Gaza Strip. She lectured and advised on MCH in over 70 countries. In 1978, she retired 'except on demand' - and of course, she was very much in demand. From the 1950s on she was awarded many fellowships and tributes; at her 90th-birthday symposium at Somerville College, guest speakers - friends and admirers - assembled like an international Who's Who of MCH and nutrition.
