Louisa Garrett Anderson, like her mother, entered the medical profession and achieved prominence as a talented surgeon. She studied at St Andrews and in Paris before attending Bedford College, London, to prepare for entry to medical school. In 1892 she entered the London School of Medicine for Women, where her mother was Dean.
Later, she became a prominent and militant suffragette who was imprisoned for her actions in 1912. On the outbreak of war, she founded the Women's Hospital Corps and set up a hospital in London to treat wounded soldiers, where she served as chief surgeon. Between 1915 and 1921 she performed nearly 7000 operations at the hospital.
A plaque celebrating the life and work of Louisa Garrett Anderson can be found opposite 65 Endell Street, the site of the military hospital she established.
