Abraham de Moivre (26 May 1667 in Vitry-le-François, Champagne, France – 27 November 1754 in London, England; ) was a French mathematician famous for de Moivre's formula, which links complex numbers and trigonometry, and for his work on the normal distribution and probability theory. He was elected a Fellow of the Royal Society in 1697, and was a friend of Isaac Newton, Edmund Halley, and James Stirling. Among his fellow Huguenot exiles in England, he was a colleague of the editor and translator Pierre des Maizeaux.
The social status of his family is unclear, but de Moivre's father, a surgeon, was able to send him to the Protestant academy at Sedan (1678-82). De Moivre studied logic at Saumur (1682-84), attended the Collège de Harcourt in Paris (1684), and studied privately with Jacques Ozanam (1684-85). It does not appear that de Moivre received a college degree.
Throughout his life he remained poor. It is reported that he was a regular customer of Slaughter's Coffee House, St. Martin's Lane at Cranbourn Street, where he earned a little money from playing chess.
De Moivre wrote a book on probability theory, entitled The Doctrine of Chances. It was said that his book was highly prized by gamblers. It is reported in all seriousness that de Moivre correctly predicted the day of his own death. Noting that he was sleeping 15 minutes longer each day, De Moivre surmised that he would die on the day he would sleep for 24 hours. A simple mathematical calculation quickly yielded the date, 27 November 1754. He did indeed pass away on that day.
He first discovered the "closed form" expression for Fibonacci numbers linking the nth power of phi to the nth Fibonacci number.
