In 1924, a small aluminum foundry was started in a garage to produce cast aluminum sugar wafer plates primarily for Nabisco’s Sugar Wafer Cookie. Aluminum was an immediate cost savings over the old heavy brass plates. During 1927, the two sons built a three-story building on Chicago’s North side and became known as Weidenmiller Bros. Foundry. The first floor housed a brass, bronze and aluminum foundry, and, the second floor, the machine and engraving shop.
