Born to a wealthy family, iconic French writer Marcel Proust (1871-1922) studied law and literature. His social connections allowed him to become an observant habitué of the most exclusive drawing rooms of the nobility, and he wrote social pieces for Parisian journals. He published essays and stories, including the story collection Pleasures and Days (1896). He had suffered from asthma since childhood, and c. 1897 he began to disengage from social life as his health declined.

Half-Jewish himself, he became a major supporter of Alfred Dreyfus in the affair that made French anti-Semitism into a national issue. Deeply affected by his mother's death in 1905, he withdrew further from society. An incident of involuntary revival of childhood memory in 1909 led him to retire almost totally into an eccentric seclusion in his cork-lined bedroom to write À la recherche du temps perdu (in English: In Search of Lost Time or Remembrance of Things Past ). Published between 1913 and 1927, the vast seven-part novel is at once a kind of autobiography, a vast social panorama of France in the years just before and during World War I, and an immense meditation on love and jealousy and on art and its relation to reality. One of the supreme achievements in fiction of all time, it brought him worldwide fame and affected the entire climate of the 20th-century novel. Biography from Encyclopedia Britannica
