Boullée, Etienne Louis
Along with Claude-Nicolas Ledoux, he was one of the leading figures of neoclassical architecture in France. He designed dream buildings combining Enlightenment philosophy, a love of geometry and a gigantic scale. A good example of his own style can be found in his design for a cenotaph for Isaac Newton, which would have taken the form of a sphere 150 metres in diameter, set on a circular base crowned with cypress trees. The design was never realized, but it was engraved and circulated widely in professional circles.
