content: Plastics made from the casein in cow’s milk began with a German patent in 1899. Alexander S. Zimmerman (1893-1979), an American specialist in the technology of cast phenolic, visited Germany shortly after World War I, and brought back a process for making plastics from casein, a thermoset material derived from the protein of cow’s milk. He then formed the Karolith Corporation to produce casein plastics. The firm, located in Long Island City, N.Y., donated this to the Smithsonian in 1926.
