Portrait of French author Marcel Proust, seated with his hand resting thoughtfully against his chin, wearing a dark suit and looking directly at the camera. — Marcel Proust French author Marcel Proust wrote what is considered one of the supreme achievements of modern fiction, the seven-part autobiographical novel *À la recherche du temps perdu* (1913–27; *In Search of Lost Time*).

Marcel Proust was an active supporter of the Dreyfus affair movement, which sought to exonerate the unjustly imprisoned army officer Alfred Dreyfus.2

During the height of the controversy between 1897 and 1899, Proust contributed to the campaign in the following ways:

Organizing and Petitioning: He helped organize petitions demanding a revision of the trial, including signing a petition alongside approximately 3,000 other individuals.12
Legal Assistance: He provided direct support to Dreyfus’s lawyer, Fernand-Gustave-Gaston Labori.2
Moral Courage: By taking these actions, Proust defied the risk of social ostracism, demonstrating a commitment to the principle of individual freedom against the pressures of the military and nationalist establishment.12

This experience was significant for Proust, as it helped crystallize his disillusionment with the aristocratic society he observed, a theme that later became prominent in his literary work.2
