text: Margarine originated with the discovery by French chemist Michel Eugène Chevreul in 1813 of margaric acid (itself named after the pearly deposits of the fatty acid from Greek μαργαρίτης or μάργαρον (margaritēs / márgaron), meaning pearl-oyster or pearl, or μαργαρίς (margarís), meaning palm-tree, hence the relevance to palmitic acid).
