Frederick reorganized the Prussian Academy of Sciences (Berlin Academy) and attracted many scientists to Berlin. Around 1751 he founded the Emden Company to promote trade with China. He introduced the Friedrich d'or, a lottery, fire insurance, and a giro discount and credit bank to stabilize the economy. One of Frederick's achievements after the Seven Years' War included the control of grain prices, whereby government storehouses would enable the civilian population to survive in needy regions, where the harvest was poor. He commissioned Johann Ernst Gotzkowsky to promote the trade and — to take on the competition with France — put a silk factory where soon 1,500 people found employment. Frederick the Great followed his recommendations in the field of toll levies and import restrictions. When Gotzkowsky asked for a deferral during the Amsterdam banking crisis of 1763, Frederick took over his porcelain factory, now known as KPM.
