The Vulcain company was founded in 1858 in Chaux-de-Fonds by Maurice Ditisheim and was also called Ditisheim Frères. An advertisement in the Almanach des Horlogers (St. Imier 1888) mentioned them as a Fabrique d’Horlogerie and they both bought and sold. In 1894, the Maurice Ditisheim company and the company Ditisheim Frères, Fabrique Vulcain, combined forces, the name becoming Maurice Ditisheim, Fabrique Vulcain. Maurice Ditisheim exhibited watches at the 1893 Columbian World Exhibition in Chicago.
