Jacob Mayer Rothschild, the youngest son, settled in Paris in 1812 where his name Jacob was translated to James. In 1817, he formally created the bank, de Rothschild Frères whose partners were brothers Amschel of Germany, James of France, Carl of Naples, Nathan of England and Salomon of Austria. Highly successful as lenders and investors, the Paris operation also became bankers for Leopold I of Belgium. In 1822 the influential James and his four brothers were awarded the hereditary title of "Baron" by Emperor Francis I of Austria.
