Marcel Proust was born in Auteuil in 1871. In his twenties, he became a conspicuous society figure, frequenting the most fashionable Paris salons of the day. From 1907, however, he rarely emerged from a cork-lined room in his apartment on the Boulevard Hausman. He slept by day and worked by night, writing letters and devoting himself to the completion of A la Réchèrche du Temps Perdu. He died in 1922 before the publication of the last three volumes of his great work.
