We had a friend visit overnight and conversation ranged widely. Including the question, ‘Who invented the Pie Chart?’
Me, stumped. Answer proffered – Florence Nightingale. Well, well. That’s a good question for my blog readers, said I. Better do a bit of googling on the topic.
What do you think? Is it likely or unlikely that she’s credited with inventing the pie chart.
As with many things, it’s not quite so straightforward to say that Florence Nightingale didn’t invent the pie chart. Having the education, skill, and interest in mathematics she used this knowledge to enable her to better argue that more soldiers died of poor hygiene in military hospitals than from wounds. She used a polar chart – see image [click to expand] – to describe Diagram of the Causes of Mortality in the East. Therefore, it’s not unreasonable to credit Florence Nightingale with furthering the use of pie charts.
