Jacques Lemercier (French pronunciation: [ʒak ləmɛʁsje]; c. 1585 in Pontoise – 13 January 1654 in Paris) was a French architect and engineer, one of the influential trio that included Louis Le Vau and François Mansart who formed the classicizing French Baroque manner, drawing from French traditions of the previous century and current Roman practice the fresh, essentially French synthesis associated with Cardinal Richelieu and Louis XIII.
