1914 - Walter Guillaume takes control

 After the death of Franz Guilleaume in 1914, his son, Walter, takes control of the factory "Franz Anton Mehlem". Many innovations are initiated following the acquisition. One such innovation includes production trials in the field of grinding products. The experience gained in the manufacture of ceramics and porcelain is exploited here. New methods are also explored in other areas. This enables improved production methods and strengthens international sales.
