Francois-Claude Theremin Theremin was the son-in-law of Jean-Guillaume-Georges Krüger. Together with the brothers André and Jean-Louis Jordan he founded an important manufactory for ornaments and jewellery in Berlin, where they employed craftspeople from Paris and Geneva. Around 1794 Theremin went into partnership with his brother Pierre, who had a workshop in St. Petersburg. They decorated their gold boxes with neoclassical Geneva style enamelling and these boxes were a great success. The brothers possibly marked their products with the initials "JT".
