Mary Frances Lucas Keene FRCS (15 August 1885 – 9 May 1977) was professor of anatomy at the London School of Medicine for Women, the first woman professor of anatomy in the United Kingdom, first woman president of the Anatomical Society of Great Britain and Ireland, and a president of the Medical Women's Federation.
At the outbreak of war in 1914, she was invited back to the London School of Medicine for Women as assistant to the professor of anatomy, Frederic Wood Jones.
His wartime work at the military hospital in Shepherd's Bush meant that increasingly Lucas was left on her own to run the department.
[1] During two summer vacations she went with the Dean of the school, Louisa Aldrich-Blake, to volunteer at Royaumont Abbey in northern France, where the Scottish Women's Hospitals for Foreign Service ran a large hospital for casualties.
In 1916 she married Richard Keene, and in 1919 was appointed head of department when Wood Jones moved to Manchester.
