Émile Pereire and his brother Isaac Pereire were major figures in the development of France's finance and infrastructure during the Second French Empire. The Pereire brothers challenged the dominance of the Rothschilds in continental European finance, known at the time as haute finance. Their attempt was temporarily successful, and even though it collapsed in the late 1860s, it contributed to a more developed and vibrant economic landscape. Like the Rothschilds, the Pereires were Jews, but unlike them, they were Sephardi of Portuguese origin.
