William Playfair
From Wikipedia, the free encyclopedia
- This article is about the inventor of statistical graphics. For the architect, see William Henry Playfair.
William Playfair (September 22, 1759 - February 11, 1823) was a Scottish engineer and political economist who made important inventions in the field of information graphics.
Playfair, who argued that charts communicated better than tables of data, has been credited with inventing the bar chart and the pie chart. His time series plots are still presented as models of clarity.
Playfair first published The Commercial and Political Atlas in 1786, in London. It contained 43 time series plots and one bar chart, a form apparently introduced in this work. It has been described as the first major work to contain statistical graphs.
Playfair's Statistical Breviary, published in London in 1801, contains what Tufte (2001) claims is the first pie chart.

[edit] Life
Spence & Wainer (in Statisticians of the Centuries) describe Playfair as "engineer, political economist and scoundrel" while "Eminent Scotsmen" calls him an "ingenious mechanic and miscellaneous writer." It compares his career with the glorious one of his older brother John Playfair, the distinguished Edinburgh professor, and draws a moral about the importance of "steadiness and consistency of plan" as well as of "genius."
William was the fourth son of the Reverend James Playfair of the parish of Liff & Benvie near the city of Dundee, Scotland. The Reverend James died when William was small and his education was "superintended" by his brother John. William's career as an engineer took him from working for James Watt as draftsman and personal assistant to making inventions. He spent an eventful time in Paris, taking part in the storming of the Bastille. In London he opened a "security bank" which failed. He was a prolific writer from an early age and in the latter part of his life supported himself by writing. (The works for which he is now famous are not mentioned in the obituary and they only began to be appreciated in the twentieth century.)
William's other notable brother was the architect James Playfair.
