Bellhouse and Christian Genest Abstract. November 27, 2004, marked the 250th anniversary of the death of Abraham De Moivre, best known in statistical circles for his famous large-sample approximation to the binomial distribution, whose generalization is now referred to as the Central Limit Theorem. De Moivre was one of the great pioneers of classical probability the- ory. He also made seminal contributions in analytic geometry, complex analysis and the theory of annuities. The first biography of De Moivre, on which almost all subsequent ones have since relied, was written in French by Matthew Maty. It was published in 1755 in the Journal britannique. The authors provide here, for the first time, a complete translation into English of Maty’s biography of De Moivre. New mate- rial, much of it taken from modern sources, is given in footnotes, along with numerous annotations designed to provide additional clarity to Maty’s biography for contemporary readers.

R. BELLHOUSE AND C. GENEST in some places. In spite of appearances, the biogra- phy of Maty (1755) predates the eulogy of Fouchy (1754) considerably, since the 1754 volume of the Histoire de l’Acad´emie royale des sciences which carried Fouchy’s article was actually published in 1759. Since De Moivre’s times, concise descriptions of his life and works have been published in several bio- graphical dictionaries, the most recent being Schnei- der (2004). Maty’s article is the major source for almost all of them and remains, to this date, the best and most complete description of this great Abraham De Moivre 1667–1754 mathematician’s life (Schneider, 2001).
