History
Philippe de Lahire was born in Paris. Although he was a cartographer, he owes his reputation above all to his work in mathematics with the publication in 1673 of his Nouvelle Méthode de Géométrie pour les sections de superficies coniques et cylindriques. Elected to the Académie des Sciences in 1678, he wrote more than 80 treatises, mainly on curve and cone sections. Lahire also taught at the Collège Royal de France and at the Académie de l'Architecture.
