Emil Hemming
Molded Electrical Insulation and Plastics
Inducted 1974
Emil Hemming (1881 – 1964) was a pioneer developer of cold-molded bituminous plastic (1905). In France, he developed the art of cold molding and, as an employee of Pathe Freres, produced the first record disc in 1990. He came to America in 1908 and founded Hemming Mfg. Co. (later Barsfield Mfg. Co.), American Insulator Co. in 1914, Newark Die Co. in 1918, and Plastics Products Co. in 1930. He authored the first book on plastics, Molded Electrical Insulation and Plastics, in 1914. The use of cold-molded plastics in electrical insulation was popular because of their heat resistance.
