Via Organs of Paris:
Marie Antoine Louis Suret (1807-1876) was a Parisian organbuilder in the first half of the 19th century. He is mentioned as early as 1827 as an organbuilder. He worked a few years as a foreman for the Daublaine and Callinet firm and started his own company in 1838. His instruments won several prizes, e.g. at the world exposition of 1855 for the organ of Ste Elisabeth, built with his son Marie François Auguste (born in Paris in 1831). The Suret company worked on approximately 50 instruments (construction as well as restoration), primarily in the Parisian region. The most remarkable instruments of Suret are:
•Saint-Basile (Étampes, 1849, III/24)
•Sainte-Élisabeth-de- Hungary (Paris, 1853, III/39)
•Basilica of Argenteuil (Argenteuil, 1867, III/31)
