This photograph was taken for a booklet promoting the work of the South London Hospital for Women and Children, produced in collaboration with the German exile photographer, Grete Stern. It shows light treatment for children suffering from vitamin deficiencies, a standard cure at the time. The South London Hospital was founded in 1912 “to meet the growing demand of women for medical treatment by members of their own sex”. Tudor-Hart campaigned throughout her life for health reforms for women and children, part of a wider movement of women whose activity was vital to the formation of the National Health Service in 1948.
