The telegram arriving in Mulhouse in October 1894 altered the life of the director of the family cotton business, Mathieu Dreyfus. Summoned to Paris by his sister-in-law, he confronted the sudden arrest of his brother Alfred for treason. This event forced the industrialist to pivot from textile manufacturing into a decade-long struggle against the French military establishment.
Early Industry and Education
Born in 1857 in Mulhouse, Mathieu Dreyfus belonged to a family of textile manufacturers. His formal education took place at the Collège Sainte-Barbe and Lycée Chaptal in Paris after his family moved from Alsace following the 1870 Franco-Prussian War. By 1885, he served as the director of the family firm, managing operations alongside his brothers Jacques and Léon. His professional trajectory was marked by his marriage in 1889 to Suzanne Marguerite Schwob, a member of a textile manufacturing family from Héricourt.

After Alfred’s arrest, Mathieu rejected the official narrative of guilt. He attempted to negotiate with Commandant Armand du Paty de Clam to verify the charges directly, though the request was denied. Recognizing that military secrecy served as a barrier to justice, he engaged political figures like Joseph Reinach and the journalist Bernard Lazare. He utilized unconventional tactics, including the dissemination of pamphlets and the placement of posters in Paris to identify the true author of the bordereau, later identified as Ferdinand Walsin Esterhazy.
Political and Legal Advocacy
Mathieu's efforts included hiring independent graphologists to challenge the incriminating evidence used against his brother. His pressure led to the involvement of high-profile figures such as Auguste Scheurer-Kestner, the vice-president of the Senate. Despite the army's resistance, the mounting public scandal surrounding the Dreyfus affair eventually led to a retrial in Rennes in 1899. Following this proceeding, Mathieu persuaded Alfred to accept a presidential pardon offered by Prime Minister Waldeck-Rouseau, preceding his brother's full rehabilitation in 1906.
Final Years
Following the resolution of the legal crisis, Mathieu returned to his industrial pursuits. The outbreak of World War I in 1915 resulted in the German authorities seizing the family's cotton business in Mulhouse. His personal life was also affected by the conflict, as his son Émile died while serving in the French artillery on October 22, 1915. Mathieu Dreyfus died in 1930 in the 16th arrondissement of Paris.
