Dollfus-Mieg et Compagnie (abbreviated as DMC), is an Alsatian textile company created in Mulhouse, France in 1746 by Jean-Henri Dollfus. During the twentieth century, it was one of the largest European textile and industry groups. DMC was the owner and then shareholder of the Ronchamp coal mines. Listed on the Paris stock exchange since 1922, it merged with the Lille company Thiriez and Cartier-Bresson in 1961. After going through a crisis in the 1990s, the old company was liquidated in 2009. In September 2016, the British investment fund BlueGem Capital Partners purchased 100% of the capital of DMC.
