Sometime in the 1860s the enterprising French chemist Hippolyte Mège-Mouriès made an important discovery. He took a pound of beef tallow soaked beforehand in a solution of 15 percent common salt and 1 percent sulfate of soda, slowly rendered it at 103 degrees Fahrenheit, poured in gastric juices of a pig, and sprinkled it with biphosphate of lime. This curdled mixture he spun in a centrifuge before adding a splash of cream. The resulting opalescent, jelly-like substance tasted much like butter.
This substance not only won Mège-Mouriès a prize offered by Emperor Napoleon III, who desperately sought a cheap, long-lasting, and easy-to-produce substitute for butter to feed the poor and his antsy army; it also secured him a place in history as the father of oleomargarine, which he patented in 1869. Two years later he sold the patent. Not long after a German pharmacist, who adapted the Frenchman’s formula, commenced its industrial production by establishing the Benedict Klein Margarinewerke.
