The Polar Area Diagrams of Florence Nightingale
If you read the article on Florence Nightingale in “The Children’s Book of Famous Lives”1 you will not learn that she had to battle with her parents to be allowed to study Mathematics. If you read the Ladybird book “Florence Nightingale”2 you will not discover that she was the first woman to be elected as a Fellow of the Royal Statistical Society. In looking around for an area of research I was intrigued to discover that Florence Nightingale, who I always thought of as the “lady with the lamp”, was a competent Mathematician who created her own type of statistical diagram which she used to save thousands of soldiers from needless death. Florence Nightingale headed a group of 38 nurses who went to clean up the hospitals for the British soldiers in the Crimea in 1854. She found that most of the deaths were due to diseases which could be prevented by basic hygiene, such as typhus and cholera. Her improvements were simple but they had an enormous effect: “She and her nurses washed and bathed the soldiers, laundered their linens, gave them clean beds to lie in, and fed them”3. When she returned to Britain she made a detailed report to the Government setting out what conditions were like and what needed to be done to reduce deaths in the hospitals. Nothing was done, so she tried again, making another statistical report and included in it three new statistical diagrams to make data collated by William Farr more accessible to people who could not get their minds around tables of figures. These were her polar area diagrams or rose diagrams, sometimes also known as ‘coxcombs’. The first showed how many men had died over the two years 1854-5, the second showed what proportions of men had died from wounds in battle, from disease and from other causes, the third showed how the number of deaths had decreased once “sanitary improvements”4 had been introduced. I decided I would try to recreate the second of
