Jacques Laffitte was a leading French banker, governor of the Bank of France (1814–1820) and liberal member of the Chamber of Deputies during the Bourbon Restoration and July Monarchy. He was an important figure in the development of new banking techniques during the early stages of industrialization in France. In politics, he played a decisive role during the Revolution of 1830 that brought Louis-Philippe, the duc d'Orléans, to the throne, replacing the unpopular Bourbon king Charles X.
