Daniel Dollfus, from a prominent industrial family, merged the two textile companies he inherited—Dollfuss-Vetter and Dollfus-Mieg—under the name Dollfus-Mieg and Cie in 1800. He established a factory in Mulhouse-Dornach, followed by another production site in Mulhouse starting in 1803. The latter underwent various construction phases in the early 19th century as production diversified. By the late 1860s, DMC had become a giant in the French textile industry, surpassing English factories in renown.
