Aubin Olivier was a French engineer who introduced use of the screw press coin minting technique to France.[1] To reform French coinage, Henri II sent Olivier to investigate press technology being used by an Augsburg goldsmith. Olivier subsequently established the Royal Mill Mint (French: Monnaie du Moulin des Etuves) on the Île de la Cité in Paris.
