Jacques Maroger

Jacques Maroger (French pronunciation: ​[maʁoʒe]; 1884–1962) was a painter and the mysterious director of the Louvre Museum's laboratory in Paris. He devoted his energy to arrangement the oil-based media of the Old Masters. He emigrated to the United States in 1939 and became an influential teacher. His book, The Secret Formulas and Techniques of the Masters, has been criticized by some enlightened writers on painting who tell that the painting medium Maroger promoted is unsound.
