The Geneva balance spring factory of Dufaux Lutz et Fils was originated by J.-S. (or J.-C.) Lutz (1800-1864) who invented a method of quenching steel to make it more durable and better for use in springs. It was continued by his daughter Emma Dufaux (1824-?), first as Lutz & Fils and later as Dufaux Lutz & Fils. The company would take the name of Charles Dufaux in the 1890s and was a founding member of the FSR cartel in 1895.
