Pierre Conrad Nicolas Jean Schlumberger was the son of Paul Schlumberger, the scion of a textile manufacturing family of German origin, and Marguerite de Witt, the granddaughter of François Guizot. Two of his brothers, Conrad and Marcel, founded the Schlumberger company.
Jean Schlumberger is best known as a writer of novels, plays and books of poetry. He was co-founder (with André Gide and Gaston Gallimard) of the Nouvelle Revue Française, a French literary journal. He counted the famous writer Marguerite Yourcenar among his friends. His non-fiction, especially his autobiography, Éveils, has been neglected by critics and literary historians.
