LAMBERT (Anna Thérèse de Marguenat de Cour-
celles, marchioness of), an elegant moral writer, was
the only daughter of Stephen Marguenat lord of Cour-
celles. In 1666 she married Henry de Lambert, who
at his death was lieutenant-general of the army; and
she afterwards remained a widow with a son and a
daughter, whom she educated with great care. Her
house was a kind of academy, to which persons of
distinguished abilities regularly resorted. She died at
Paris in 1733, aged 86. Her works, which are writ-
ten with much taste, judgment, and delicacy, are
printed in two volumes. The advice of a mother to
her son and daughter are particularly esteemed.
