As we are just attempting to understand how galaxy formation is connected to the growth of supermassive black holes, one fundamental challenge remains. Observations show us that the first quasars were assembled when the universe was only a tenth of its current age, yet their black holes are as massive as the ones in today’s galaxies. I will discuss state-of-the-art large-scale simulations which attempt to study directly the growth of the first, rare, supermassive black holes within the context of our standard structure formation models.
