Today's Wall Street Journal morning newsletter says, "On this day in 1667, mathematician Abraham de Moivre was born in Vitry, France. In 1688, he fled to England to escape King Louis XIV's persecution of the Huguenots. In London, de Moivre discovered the normal statistical distribution (the "bell curve") and worked out the formula for standard deviation, or short-term volatility." I had heard of the De Moivre's formula but was not aware of his other discoveries. (Is the WSJ correct in its attributions?)
