Florence Nightingale is most remembered as a pioneer of nursing and a reformer of hospital sanitation methods. She pushed for reform of the British military health-care system and with that the profession of nursing started to gain the respect it deserved. Her use of new techniques of statistical analysis, such as during the Crimean War when she plotted the incidence of preventable deaths in the military, she developed the "
polar-area diagram" to dramatize the needless deaths caused by unsanitary conditions and the need for reform. With her analysis, Florence Nightingale revolutionized the idea that social phenomena could be objectively measured and subjected to mathematical analysis. She was an innovator in the collection, tabulation, interpretation, and graphical display of descriptive statistics. She contributed to reform of hospitals (amazing considering that most women of her age did not attend universities or pursue professional careers). She spoke Italian, Latin, Greek, learned history, and mathematics. When her sanitary reform was implemented, the mortality rate declined.
