 It is unclear when de Moivre left the Prieure de Saint-Martin and moved to England, since the records of the Prieure de Saint-Martin indicate that he left the school in 1688, but de Moivre and his brother presented themselves as Huguenots admitted to the Savoy Church in London on 28 August 1687.By the time he arrived in London, de Moivre was a competent mathematician with a good knowledge of many of the standard texts.To make a living, de Moivre became a private tutor of mathematics, visiting his pupils or teaching in the coffee houses of London.
