Biography

Wire of a merchant of Low-Auvergne, he is initially clerk in various magistrates of this area. In 1675, it settles with Paris, where he becomes pupil astronomer of the royal Académie of sciences in 1685 and boarder geometrician in 1699. It receives a pension of Jean-Baptiste Colbert in 1682 after having solved one of the problems of Jacques Ozanam:

“To find four numbers such as the difference of two unspecified, is a cut, and that the sum of two unspecified of the three first is still a cut. ”

Poker very early adopted a very critical attitude with regard to the Infinitesimal calculus. In 1702, it had on this subject a controversy with Joseph Saurin. He said that he vague and was based on a defective reasoning; he changed opinion later.

“It had in 1708 an attack of apoplexy, which it left with all its spirit, and almost the same force for work. But ten years after one second attacks threw it in Paralisie, which did not enable him any more to leave, and he died the 68 years old on November 8th, 1719, after having given all the marks of a solid piety. Its manners had been such that form them a great attachment being studied, and the happy deprivation of the trade of the world.”
