Bell was a world- changer
I’m staggered your nominees failed to include Gertrude Bell (1868–1926), the most influential female diplomat of all time: she played a critical part in securing the support of Arab tribes against the Ottoman empire in the First World War. As well as being the only female at the 1919 Paris Peace Conference, she was the first woman to write a parliamentary white paper and she had a critical role as a participant at the 1921 Cairo Conference.
When not ‘changing the world’ she sourced new Alpine routes, had a peak named after her, mapped out Middle East antiquities, pioneered architectural photography, and founded the National Library of Iraq and the Baghdad Museum.
When she died, George V ranked her with Florence Nightingale and Marie Curie, but apparently she is not influential enough for BBC History Magazine. Ged Parker, Washington
