Wilson & Co.(United Products and Organic Chemicals Div.) had a gelatin plant on the border of Calumet City, ILL and Hammond, IN. It received pigskins, at one point, in refrigerator cars and produced, of course, gelatin, #1 & #2 pigskin grease and “pigskins”. The plant was switched by the IHB. The plant is still there and has changed hands 2 or 3 times and still produces the above products and some new ones. Eastman Kodak, Swift & co. and others also had gelatin plants using pigskins as raw material. Regards...Jerry Albin
