Henry Hering (1814-1893) · Public domain
Florence Nightingale
The founder of modern secular nursing: famous for Scutari, more consequential for what followed — Notes on Nursing (1859), the first secular training school at St Thomas' Hospital (1860), and decades of statistical warfare on the causes of preventable death in hospitals and armies.
After Crimea, Nightingale worked with the statistician William Farr to analyze why soldiers had died, and invented her polar-area 'rose' diagrams to show that far more men were killed by preventable disease than by wounds. She aimed the charts deliberately at Queen Victoria and cabinet ministers — readers, she judged, who would never work through tables. The campaign drove a Royal Commission on army health, and in 1858 she became the first woman elected a Fellow of the Royal Statistical Society.
“Count what is killing people, draw it so power cannot look away, and attach a reform to the chart.”
