Anne Sayre, Franklin's friend and one of her biographers, says in her 1975 book, "Rosalind Franklin and DNA: " "In 1951 ... King's College London as an institution, was not distinguished for the welcome that it offered to women ... Rosalind ... was unused to "purdah" religious and social institution of female seclusion ... there was one other woman scientist on the laboratory staff". The molecular biologist Andrzej Stasiak notes: "Sayre's book became widely cited in feminist circles for exposing rampant sexism in science." Farooq Hussain says: "there were seven women in the biophysics department ... Jean Hanson became an FRS, Dame Honor B. Fell, Director of Strangeways Laboratory, supervised the biologists". Maddox states: "Randall ... did have many women on his staff ... they found him ... sympathetic and helpful."
