Louis Sonnery‑Martin (born 8 September 1848 in Tarare, Rhône – died 9 May 1919 in Lyon, Rhône) was a French industrialist and local‑political figure of the late 19th and early 20th centuries.
Early life and family
Sonnery‑Martin was the youngest of three sons of Jean Sonnery and Marie Thérèse Martin. He married Marie‑Thérèse Martin on 5 February 1869 in Tarare.
Industrial career
From 1872 to 1881 he managed the velvet‑and‑plush manufacturing business of his father‑in‑law, the Martin company, based in Tarare. Under his direction the firm expanded its production of textile goods and contributed to the economic development of the region. His business activities earned him the presidency of the Chamber of Commerce of Tarare, recognizing his role in promoting local commerce and industry.
Political career
In 1882 Sonnery‑Martin was elected general councillor for the canton of Tarare in the Rhône department, succeeding Nicolas‑Marie Sève. He held the seat for several terms, participating in departmental deliberations and representing the interests of his constituency.
Later life and legacy
In 1906 he purchased the Château de Chaintré, a 12th‑century estate located in Crêches‑sur‑Saône (Saône‑et‑Loire). The château later became associated with the wine industry of the region. Sonnery‑Martin’s descendants continued his industrial involvement; his son René Sonnery‑Martin (1887‑1966) served as president of the Société Chimique des Produits de Lion Noir.
