Florence Nightingale’s wealthy family was disappointed and disapproving of her desire to work – and nursing? They just couldn’t fathom it. Despite their disapproval, she followed her heart, becoming known as “The Lady With The Lamp” while nursing in the Crimea. Her greatest achievement was to transform nursing into a respectable profession for women. A great statistician, Florence also invented the pie chart and was the first woman elected to the Royal Statistical Society. She was also the first woman awarded the Freedom of the City of London, in 1909.
